Autosomal dominant

Also found in: Acronyms.

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.

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 dominant

Pert. to or characteristic of an autosomal dominant gene.
See: autosomal dominant gene

Autosomal dominant or autosomal recessive

Refers 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.
