Predicting the effects of noncoding variants in Human Cardiac Disease

Towards A Future With Millions Of Human Genomes Sequenced

IQCC Science Slam, Girona, 24/11/2016 – Research Project by Sara Pagans & Miquel Duran

The Challenges• We Know the Letters, We Do Not Know Most of the Words, We Do

Not Understand Most of the Sentences

• There Is Not A “Single” Human Genome, Every Person Has His/Her Own Genome

• There is a Coding Fraction in the Genome that We Understand, But Only Represents 1-2% Genome

We Are Trying to Understand the Meaning of Noncoding Words and Sentences

Many ‘Words’ Have Meaning Regarding Transcription Factors Binding and Binding Strenght

Correct gene expression is very important for human biology.

Model System of Our Analyses: Cardiac Cells and Sudden Cardiac Death

• Sudden stop of heart beating without any previous symptoms. • 800,000 deaths occur annually in the Western World.• Mainly affects men in their 40’s or younger and kids/babies.
