gene disorder inherited through autosomal inheritance
Genetic disorders can be inherited in different ways: autosomal dominant, autosomal recessive, X-linked, and mitochondrial patterns of inheritance. In an autosomal dominant pattern of inheritance, a child inherits a normal copy of a gene from one parent and an abnormal gene from the other parent.The abnormal gene dominates the normal gene, so one copy of an abnormal gene is enough to cause an autosomal dominant disorder (Figure 1).utosomal dominant inheritance. When a disorder is passed on in an autosomal recessive fashion, two copies of the abnormal gene are required to cause the disorder. Individuals who inherit only one abnormal gene and one normal gene are referred to as carriers and are. affected by the disorder.
