Autosomal Recessive Inheritance

In this example, two unaffected parents each carry one copy of a gene mutation for an autosomal recessive disorder. They have one affected child and three unaffected children, two of which carry one copy of the gene mutation.

Examples of Autosomal Recessive Disease

• Cystic fibrosis (CF) (More? respiratory}

• Sickle cell anaemia (More? blood)

• Tay-Sachs disease (More? neural}

Preconception carrier tests are available for some autosomal recessive (AR) diseases. These tests were initially developed for autosomal recessive diseases that were frequent in specific ethnic groups:

• Tay–Sachs disease - Ashkenazi Jews
• hemoglobinopathies - Mediterranean and African populations
• cystic fibrosis - European-derived populations
