Autosomal dominant
autosomal dominant adjective Referring to a trait or disorder that may be passed from one generation to the next when only one allele is required to pass a genetic defect to the progeny. Examples Achondroplasia, Huntington’s disease, Marfan syndrome, neurofibromatosis, osteogenesis imperfecta.autosomal dominant Genetics Referring to a mode of inheritance, in which the presence of only one copy of a gene of interest on one of the 22 autosomal–non-sex chromosomes, will result in the phenotypic expression of that gene; the likelihood of expressing an autosomal gene in progeny is 1:2; ♂ and ♀ are affected equally. Cf Autosomal recessive, X-linked recessive. autosomal dominantPert. to or characteristic of an autosomal dominant gene. See: autosomal dominant geneAutosomal dominant or autosomal recessiveRefers to the inheritance pattern of a gene on a chromosome other than X or Y. Genes are inherited in pairs—one gene from each parent. However, the inheritance may not be equal, and one gene may overshadow the other in determining the final form of the encoded characteristic. The gene that overshadows the other is called the dominant gene; the overshadowed gene is the recessive one.Mentioned in: Cerebral Amyloid Angiopathy, Hereditary Hemorrhagic Telangiectasia, Ichthyosis, Muscular Dystrophy, Peripheral Neuropathy, Porphyrias, Prolonged QT Syndrome, Tourette Syndrome, Von Willebrand Disease, Waldenström's MacroglobulinemiaAcronymsSeeAD |
