What are some of the different types of autosomal recessive disorders? Examples of autosomal recessive disorders include cystic fibrosis, sickle cell anemia, and Tay-Sachs disease. The gene is on an autosome, a nonsex chromosome. In the case of autosomal dominant disorders, males and females will also be equally affected. The parents of an individual with an autosomal recessive condition each carry one copy of the altered gene, but they typically do not show signs and symptoms of the condition. Many important and well-understood genetic diseases are the result of a mutation in a single gene. If a genetic condition only occurs when both copies of the gene have a change in the message, this change is called a recessive variant. Illustration demonstrating how genes are passed down from parents to children.
The terms autosomal dominant or autosomal recessive are used to describe gene variants on non-sex chromosomes and their associated traits, while those on sex chromosomes (allosomes) are termed X-linked dominant, X-linked recessive or Y-linked; these have an inheritance and presentation pattern that depends on the sex of both the
