Health Mrs. Wagner
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
