Step-wise conditional analyses in HLA region and HLA fine-mapping

Step-wise conditional analyses were conducted including 21,912 SNVs/INDELs

within the HLA region (Hg19: chr6: 29,640,147–33,115,544 bp). The HLA class II region

exhibited the most significant association and the HLA class I region showed

independent but moderate significance after conditioning on top SNPs (Supplementary

Figure S9A-G, Supplementary Table S9).

HLA fine-mapping was performed in the discovery sample set by imputing

classical HLA genes (HLA-A, -C, -B, -DRB1, -DQB1, -DPA1 and -DPB1). Overall, 870 cases

and 2,903 controls passed the post-imputation QC (call threshold >0.4).

Significantly associated HLA alleles were identified in six HLA genes except for

HLA-DPA1 (Supplementary Tables S11-S13). HLA haplotypes were generated and

association analyses were conducted (Supplementary Table S10, Supplementary Tables

S14–S19). As we emphasized in our previous workS1, HLA-DRB1*08:02-DQB1*03:02 was

the most significant susceptibility haplotype (Pc=1.16E-22, OR=3.38), with a more

significant and stronger association than HLA-DRB1*08:02 (Pc=2.60E-22, OR=2.66) or

HLA-DQB1*03:02 (Pc=2.59E-10, OR=1.71) alone. HLA-DRB1*13:02-DQB1*06:04 was the

most significant protective haplotype (Pc=1.63E-16, OR=0.18). One individual in the

case group (1/870=0.11%) and 15 healthy controls (15/2,903=0.52%) were

heterozygotes for HLA-DRB1*08:02-DQB1*03:02 and HLA-DRB1*13:02-DQB1*06:04,

suggesting a dominant effect of the protective haplotype over the susceptibility

haplotype although the difference was not statistically significant (P=0.14,

Supplementary Table S20).

Supplementary Methods

Samples and clinical data

In the discovery stage, 1,018 Japanese patients diagnosed as childhood SSNS

were recruited from 67 hospitals throughout Japan. Clinical data for the patients were

collected using a simple questionnaire. Genomic DNA was extracted from peripheral

blood following a standard protocol.

Overall, 3,331 Japanese healthy adults (>18 years) who passed childhood

without disease onset were recruited as controls; 419 healthy adults were collected

from Tokyo, Japan (Tokyo Healthy Control, THC), referred by the Department of Human

Genetics, Graduate School of Medicine, The University of Tokyo; 1,857 Japanese adults

were provided by Tohoku Medical Megabank Project (TMM)S2; 384 healthy controls

were provided by PharmaSNP Consortium, Japan; and 671 controls were provided by

Nagasaki Medical Center, Japan.

This study was approved by the Research Ethics Committees of Kobe

University Graduate School of Medicine and the Graduate School of Medicine, The

University of Tokyo, and all collaborating universities and hospitals. All participants

provided written informed consent for participation in this study.

Genotyping and whole-genome imputation in the discovery stage

In the discovery stage, 1,018 patients with childhood SSNS and 3,331 healthy

adult controls were genotyped using the Affymetrix ‘Japonica Array’S3, which was

specially designed for the Japanese population based on the whole-genome sequencing

data of 1,070 healthy Japanese individuals. The 384 controls samples from

PharmaSNPConsortium were genotyped by Japonica Array V2, while the rest of the

samples were genotyped by Japonica Array V1. Genotyping was performed for each SNP

array using Affymetrix Power Tools version 1.17.0 (Thermo Fisher Inc.) according to the

manufacturer’s instructions. All genotyped samples passed the recommended sample

Page 12: Supplementary Material - ars.els-cdn.com€¦ · 20. Department of Pediatrics, Wakayama Medical University, Wakayama, Japan. 21. A list of members and affiliations appears in the

12

QC metric for the AXIOM arrays (dish QC >0.82). We conducted the genotyping of QC

markers as recommend by the manufacturer’s instructions. Nineteen samples (16 and

three samples from Japonica Array V1 and V2, respectively) with an overall call rate

<97% were excluded in this step. The genotyping of all SNPs was then conducted for the

remaining samples and all the samples had an overall call rate ≥97%. Nine controls with

ambiguous sex were excluded. The genotype data were then merged into a single file by

extracting the overlapping SNPs between both SNP arrays. Because most of the SNP

probes designed on Japonica Array V1 and V2 were identical, 6,632,490 SNPs remained

after this process.

For imputation, the clustering plots were classified by the Ps classification

function in the SNPolisher package (Affymetrix Power Tools version 1.17.0 and Axiom

Analysis Suite 4.0). SNPs that were assigned “recommended” by Ps classification were

retained. SNPs with a call rate <99.0%, a MAF <0.5%, non-autosomal SNPs or with an

HWE test result of P<0.0001 in controls were excluded. Prephasing was conducted first

with the SNPs which passed the filtering step with EAGLE (ver. 2.3.2); the options were

–burn 10, –prune 10, and –main 25. Genotype imputation was performed on the phased

genotypes with IMPUTE4S4 (ver. 2.3.1) using a phased reference panel of 2,036 healthy

Japanese individuals (2KJPN panel). For IMPUTE4, the applied options were –Ne 2000, –

k hap 1000, –k 120, –burnin 15, and –iter 50.

After whole-genome imputation, there were 22,049,786 autosomal SNVs and

short INDELs with an info score >0.5. QC was conducted using the following threshold:

individual missing rate <3% (one case and one control were excluded), SNV/INDEL call

rate ≥97% (661,512 SNVs/INDELs were excluded), MAF ≥0.5% (14,598,443

SNVs/INDELs were excluded), and HWE P-value ≥0.0001 in healthy controls (491

SNPs/INDELs were excluded). Identical-by-Descent test was performed and 101

individuals were excluded using a threshold of Pi-hat >0.1875. PCA was performed using

GCTA (Version 1.26.0)S5 for cases, controls, and HapMap Phase III data (113 CEU, 113

YRI, 84 CHB, and 86 JPT). Twenty-five individuals were identified as outliers and

excluded (Supplementary Figure S1A-E).

Genome-wide association analyses in the discovery stage

Association analyses were conducted using logistic regression, adjusting for sex

and the first four principal components (PC1 to PC4) by PLINK 1.9. All cluster plots of

genotyped SNPs with P<1E-05 were checked by visual inspection. Regional plots were

checked for each candidate region with suggestive significance (P<1E-05).

Gene-based test and gene-set analysis

Gene-based test and gene-set analysis were performed using GWAS summary

statistics by MAGMA v1.6S6 (implemented through FUMAS7). For gene analysis, a gene-

based P-value was computed for protein-coding genes obtained from Ensembl build 85

by mapping SNPs to genes if SNPs were located within the genes. For the gene set

analysis, the gene set P-value was computed using the gene-based P-value for 4,728

curated gene sets (including canonical pathways) and 6,166 GO terms obtained from

MsigDB v5.2. The Genotype-Tissue Expression (GTEx) databaseS8 and the NephVS eQTL

Browser (NephQTL)S9 were utilized to find eQTLs affecting the expression of various

genes in various tissues and kidney-specific tissues. Variants in the candidate region on

chromosome 19 (Hg19: chr19: 36.2-36.6Mb) with P-values <0.05 were checked.

Validation and replication of candidate SNPs

For technical validation, rs56117924, rs412175, rs2285450, rs404299,

rs34213471 and rs8086340 were genotyped in 224 cases in the discovery sample set

while rs2073901 was genotyped in 96 healthy controls in the discovery sample set by

Taqman assay. Candidate variants were genotyped successfully with a mean

concordance rate of 99.3% (96.8%–100%).

An international collaboration was carried out to replicate the detected signals

in multiple populations. Participants in the Korean dataset were recruited from the

South Korea. The MWPNC (Midwest Pediatric Nephrology Consortium) cohort included

181 patients of South Asian ancestry recruited from the USA and Sri Lanka, 158 patients

of African ancestry recruited from the USA and Nigeria, and 63 European and 27

Hispanic patients recruited from the USA. The NEPHROVIR (Children Cohort Nephrosis

and Virus) cohort included 132 European, 56 African and 85 Maghrebian children with

SSNS, which were recruited in the Paris area (Ile-de-France), 2000 European controls

from 3 Cités, and 454 controls from the 1000G African cohort and 261 Moroccan

controls were used as population-matched controls, respectively. The ItSpa (Italian and

Spanish) cohort comprised 112 European patients from Italy and Spain and 552 controls

from the 1000G European cohortS10.

In the Korean dataset, 249 patients were included. Seven of the nine SNPs

(rs56117924, rs2073901, rs412175, rs2285450, rs404299, rs34213471 and

rs8086340) were genotyped by Taqman assay, while the genotypes of rs6478109 and

rs4979462 in the same 249 patients were extracted from existing genotype data by

Axiom Genome-Wide ASI Array. Five candidate SNPs on chromosome 19 (rs56117924,

rs2073901, rs412175, rs2285450 and rs404299) were genotyped in 380 Korean

healthy adult controls, two candidates SNPs on chromosome 18 (rs34213471 and

rs8086340) were genotyped in 665 Korean controls, and individual genotype data of

rs6478109 and rs4979462, which were genotyped in 3,805 Korean controls in a

previous study10, were utilized here. The MWPNC cohort included 181 patients of South

Asian ancestry, 158 patients of African ancestry, 63 European and 27 Hispanic patients.

For the MWPNC cohort, nine candidate SNPs were genotyped by Taqman assay. The

allele counts of candidate variants for South Asians, Europeans, Africans and Hispanics

were obtained from the public databases of Genome Aggregation Database (genomAD,

http://gnomad.broadinstitute.org), ExAC database by Exome Aggregation Consortium

Page 15: Supplementary Material - ars.els-cdn.com€¦ · 20. Department of Pediatrics, Wakayama Medical University, Wakayama, Japan. 21. A list of members and affiliations appears in the

(http://exac.broadinstitute.org) or “The South Asian Genome” dataset from South Asian

Genomes&Exomes (http://clingen.igib.res.in/sage/) as population-matched controls.

Information of candidate SNPs from the NEPHROVIR (Children Cohort Nephrosis and

Virus) and ItSpa (Italian and Spanish) cohorts in reported trans-ethnic GWAS9 was

utilized as independent replication sample sets.

Whole Genome Sequencing

Whole genome sequencing (WGS, 30x) was performed on 625 samples from

the Nephrotic Syndrome Study Network Consortium (NEPTUNES12) using the Illumina

HiSeq system. Alignment and variant calling was performed using default settings of

GotCloud with the GrCh37 reference of the human genomeS13. We then removed rare

variants (MAF < 0.0001), variants with quality score less than 20, variants with greater

than 10% missing and indels from the resulting VCFs. Finally, we used McCarthy Tools

to remove variants missing or with greater than 0.5 allele frequency difference from the

1,000 Genomes Phase 3 reference panelS14. A total of 531,420 variants on chromosome

19 were phased with Eagle v2.4.1S15 on the Michigan Imputation ServerS16using the

1,000 Genomes Phase 3 reference panelS14. Due to a high recombination hotspot within

NPHS1, we found inconsistent phasing of rs2071347 (NPHS1, exon 26) when comparing

different reference panels and methods, and thus removed it from downstream

analyses. Samples harboring all five chromosome 19 risk alleles (rs56117924,

rs2073901, rs412175, rs2285450 and rs404299) were identified.

RNA-seq

Total RNA from 269 NEPTUNE glomerular biopsies was extracted, and libraries

were prepared using the Clontech SMARTSeq v4 kit. Samples underwent sequencing

using Illumina HiSeq 2500, resulting in 150 bp unstranded, paired-end reads. Reads

found in fastq files underwent quality control filtering and trimming using fastQC,

Page 16: Supplementary Material - ars.els-cdn.com€¦ · 20. Department of Pediatrics, Wakayama Medical University, Wakayama, Japan. 21. A list of members and affiliations appears in the

16

fastQScreen, and picardtools (REFs ). Trimmed reads were then aligned to the human

genome (GRCh37) with STAR 2.6.0aS17. Gene quantification (Log2CPM) was calculated

with the edgeR TMM-normalization methodS18. The bam files were subset to NPHS1 and

the surrounding 1KB intergenic region (chr19: 36,315,274-36,343,895). The bam files

were subset to NPHS1 and the surrounding intergenic region (chr19:36,304,201-

36,358,048). Sashimi plots were visually inspected for exon skipping using IGV version

2.7.2S19, S20.

Allele-specific expression (ASE)

The NPHS1 bam files and phased WGS for 241 matched WGS-RNAseq samples

were input into phASERS21 to perform haplotype phasing. Only uniquely mapped

variants with a minimum base quality score of 10 were used. We used phASER to

calculate haplotype-specific expression by summing RNA-seq counts across all

heterozygous SNPs. Samples with less than 20 total reads across NPHS1 were removed.

For the 187 remaining samples, we calculated ASE as |0.5 – (reference reads / total

reads)|. We then compared ASE for samples with and without the risk haplotype with a

Wilcoxon rank-sum test in R. The total reads and number of supporting heterozygous

SNPs varied across samples. Samples with lower power to detect ASE, less than three

heterozygous SNPs or in the bottom 10% of total reads, were nonetheless included for

completeness and are indicated as gray points in corresponding figures.

HLA imputation and HLA genotyping

In the discovery stage, HLA imputation was performed in 987 cases and 3,206

controls to clarify the genome-wide associated signals identified in the HLA region. We

conducted 2-field HLA genotype imputation for seven classical HLA genes in HLA class I

(HLA-A, -C and -B) and class II (HLA-DRB1, -DQB1, -DPA1 and -DPB1) loci using the

“HIBAG” R package. After SNP QC (SNP call rate ≥97%, MAF ≥5%, and HWE P-value

Page 17: Supplementary Material - ars.els-cdn.com€¦ · 20. Department of Pediatrics, Wakayama Medical University, Wakayama, Japan. 21. A list of members and affiliations appears in the

17

≥0.0001 in healthy controls), SNP data for individuals were extracted from an extended

major histocompatibility complex (MHC) region, ranging from 25,759,242 to 33,534,827

bp based on the hg19 position. Our in-house Japanese imputation reference was used for

HLA genotype imputation. We applied post-imputation QC using a call threshold

(CT) >0.4 for each geneS22. Individuals were excluded from subsequent analyses if have

one or more than one gene failed in the post-imputation QC. Overall, 870 cases and

2,903 healthy controls in the discovery stage passed the post-imputation QC and were

kept in association analyses. HLA haplotypes were estimated using BIGDAWG (Bridging

ImmunoGenomic Data-Analysis Workflow Gaps) software version 2S23. HLA

allele/haplotype frequencies were compared between cases and controls. P-values were

calculated using Pearson’s chi-square test or Fisher’s exact test in the presence vs

absence of each HLA allele/haplotype. P-values were corrected for the number of

alleles/haplotypes tested in each analysis (shown as P-corrected). We considered an

association significant when the P-value was <0.05 after correction for multiple

comparisons. Rare HLA alleles/haplotypes with the total counts in cases and controls

<10 were excluded before performing association analyses. HLA alleles/haplotypes with

frequencies <0.5% in cases or controls were excluded from multiple corrections. As

validation, HLA genotyping was performed in 418 controls. The accuracy rate of HLA-

imputation with post-QC (CT>0.4) for the seven imputed genes was 99.2% (96.2%–

100%).

Heritability estimates

We used GCTAS5, S24 (GCTA-LDMS method) to estimate the heritability of

childhood SSNS explained by genome-wide variants, assuming a disease prevalence of

0.016% in the Japanese population. After whole-genome imputation, all variants passed

QC procedure were utilized in the analysis. We calculated segment-based LD scores

using a segment length of 200 kb (with 100 kb overlap between two adjacent segments).

Page 18: Supplementary Material - ars.els-cdn.com€¦ · 20. Department of Pediatrics, Wakayama Medical University, Wakayama, Japan. 21. A list of members and affiliations appears in the

18

To stratify the variants for genetic relationship matrixes (GRMs), we used two LD score

bins (≤ median LD score and > median LD score) and two MAF bins (common variants:

MAFs ≥ 0.05 and uncommon variants: 0.005 ≤ MAFs < 0.05). We then estimated the

GRMs using variants stratified into each group separately. Lastly, we performed

restricted maximum likelihood (REML) analysis using the multiple GRMs. Considering

the established strong association of the HLA region, heritability was calculated without

variants on chromosome 6 using the same criteria. GCTA uses disease prevalence to

transform the estimated heritability from the observed scale to the liability scale;

therefore, we assumed a population prevalence of 0.016% for childhood SSNS.
