autosomal dominant disorders

Autosomal dominant disorders are genetic conditions caused by a mutation in one copy of a gene located on one of the non-sex chromosomes (autosomes). This means that only one affected parent can pass the mutated gene to their child for the disorder to manifest. Each child has a 50% chance of inheriting the condition, regardless of the sex of the parent or child. Examples include Huntington's disease and Marfan syndrome. Symptoms can vary widely, and the age of onset can differ, but the presence of just one mutated copy is enough to cause the disorder.
