Genetic – Hereditary – carried on Recessive Gene – must have 2 recessive genes to get birth defect

Chromosomal – 23 pairs from each parent – 46 total

Environmental – lifestyle choices Environmental & Hereditary – cleft lip/palate

Recessive Gene (Hereditary) 1/20 Caucasian Americans carry gene Lungs make to much mucus Digestion and breathing become difficult Life expectancy – 36 years Most common deadly genetic disease Can find out during pregnancy

• Chromosomal – extra 21 chromosome• Affects physical and intellectual health• Physical: smaller eyes, forehead flatter,

pale, slurred speech, decreased vision, overweight (slower metabolism)

• Life expectancy - Early 50’s• Heart Disease – Heart Problems – biggest

risk factor• Mother’s Age – 24 – 1/2500 42 or over 1/60

Hereditary Can be fatal Affects central nervous system – doesn’t

create a protein needed by brain for dev. Normal development until 6 months – then

stop Eventually become blind and paralyzed –

die by age of 4 1 out of every 30 Jewish Americans carry

the gene

Hereditary disease that affects the red blood cells

RBC are sickle shaped and get stuck in small veins cutting off blood supplies

Common problems: Anemia, infections, pain, strokes, vision problems and slow growth

All states screen at infancy – treatment plan 1 in 12 African Americans and 1 in 100

Hispanic Americans carry the gene

Inherited disorder in which the body cannot process a protein in most foods

Testing is done on all newborns in the US – can be treated early

1 in 25,000 are born with Biggest complication – mental retardation Require a special diet throughout life

Hereditary and Environmental Affects lower back and spinal cord Occurs by itself – may be present with other

birth defects 3 types – vary in severity Problems: Hydrocephalus(fluid on brain),

back braces, wheelchair usage, learning disabilities

Most live normal life spans

Hereditary and/or environmental Group of conditions that affect movement,

coordination, balance and posture – brain damage

2 – 3 children in 1,000 are affected Risk factors: prematurity, infections during

pregnancy, severe jaundice Several problems including mental

retardation are common

Environmental 100% preventable Mental, physical & developmental problems 1 in every 1,000 live births
