Autosomal recessive disorders occur when a person has defects in both copies of an autosomal gene (a gene that is located on any of the autosomes) (Figure 3.1B), resulting in “loss of function” (Figure 3.2A).If both copies of the gene have the same deleterious mutation, the defect is termed homozygous. Sickle cell anemia 4. Autosomal dominant polycystic kidney disease (ADPKD) is a multisystem disorder characterized by the growth of numerous kidney cysts and expansion of kidney volume leading to ESKD in a majority of patients (1,2).Hypertension, gross hematuria, cyst rupture and infection, kidney stones, and flank pain are common kidney complications, whereas extrarenal manifestations include … Twice genetic autosomal dominant, X-linked dominant, X-linked recessive CADASIL ) is a searchable database of medical literature lists.
