Autosomal Dominant Inheritance

Autosomal Dominant Inheritance is a genetic inheritance pattern in which a single copy of a mutated gene located on one of the autosomes (non-sex chromosomes) is sufficient to cause a trait or genetic disorder. In this pattern, an affected individual usually has one affected parent, and each child of an affected parent has a 50% chance of inheriting the mutation and expressing the condition. Because the gene is located on an autosome, the disorder affects males and females equally and can appear in every generation of a family. Autosomal dominant conditions often show a vertical transmission pattern in pedigrees, meaning the trait is passed from parent to child across successive generations. Examples of disorders that follow this inheritance pattern include Huntington's disease, Marfan syndrome, and Achondroplasia. Understanding autosomal dominant inheritance is important for genetic counseling, disease prediction, and family risk assessment in medical genetics.
