Galactosemia 1. Is inherited how? 2. Deficiency of what? and what does this lead to? 3. Clinical presentation? 5
1. Autosomal recessive disorder 2. Deficiency of galactose-1-phosphate uridyltransferase leading to buildup of unmetabolized galactose 3. Clinical presentation - Appears within days to weeks of birth - Hepatomegaly - Vomiting, anorexia - Growth failure (failure to thrive) - Aminoaciduria
89
What happens if galactosemia pt is given milk?
unmetabolized milk sugars build up and damage the liver, eyes, kidneys and brain

Embryological disorders and CP | 3
1. Neural tube defect 2. Orofacial clefts 3. Cerebral palsy
92
What happens in a neural tube defect? Risk factors?
Failure of neural groove to fuse completely 1. Maternal age (teenage and older women) 2. Maternal health (medications, diabetes, nutrition)
93
Two major types of neural defects? How do we diagnosis prenatally? Prevention?
1. Anencephaly (no cranium) 2. Meningomyelocele (spina bifida) – distal to brain 1. Prenatal diagnosis = elevated alpha-fetoprotein 1. PREVENTION: Prenatal (antenatal) Folic acid supplementation
