Study Notes
Autosomal Dominant Disorders
- Achondroplasia: Characterized by abnormal bone growth, causing short stature (dwarfism).
- Neurofibromatosis (NF): Shows variable symptoms, including characteristic café au lait spots and benign tumors (neurofibromas) on skin and beneath.
- Marfan Syndrome: A connective tissue disorder affecting the cardiovascular system, eyes, and skeletal structure.
- Huntington's Disease: A progressive neurological disease causing nerve cell degeneration in the brain, affecting movement, thinking, and emotions.
- Familial Hypercholesterolemia: A genetic condition leading to significantly elevated cholesterol levels in the blood.
- Retinoblastoma: An eye cancer originating in the retina (back of the eye).
Autosomal Recessive Disorders
- Sickle Cell Anemia: Abnormal hemoglobin causes episodes of blood vessel blockage (vaso-occlusion) and chronic anemia.
- Phenylketonuria (PKU): An enzyme deficiency leads to phenylalanine accumulation, inhibiting brain and cognitive development.
- Tay-Sachs Disease: A fatal neurodegenerative disorder resulting from lipid accumulation due to an enzyme deficiency (Hex-A).
- Cystic Fibrosis: A multi-organ disease causing severe lung problems. Inherited through mutations in the CFTR gene.
- Gaucher Disease: A type of lipid storage disorder caused by an enzyme deficiency (GBA). Multiple subtypes exist.
- Beta-Thalassemia: Reduced hemoglobin A production, leading to anemia.
Multifactorial Conditions
- Neural Tube Defects: Develop during early fetal development from incomplete neural tube closure. Varying severity depending on the affected section (e.g., spina bifida, anencephaly).
- Congenital Heart Defects: Most congenital heart problems likely have multiple contributing factors. Specific genes are linked to certain defects (e.g., patent ductus arteriosus, septal defects).
- Cleft Lip and Palate (CL/P): Result from incomplete bony fusion during fetal development. While some rare gene mutations can cause CL/P, most cases are attributed to multiple factors.
- Autism Spectrum Disorder (ASD): The cause is not fully understood, but likely a combination of genetic and environmental influences (e.g., exposures, infections, maternal stress). Studies with twins show a significant genetic component.
