Modes of inheritance:
Autosomal dominant inheritance

Concept ID:

Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Definition

A rare genetic retinal dystrophy disorder with characteristics of bilateral microcornea, rod-cone dystrophy, cataracts and posterior staphyloma, in the absence of other systemic features. Night blindness is typically the presenting manifestation and nystagmus, strabismus, astigmatism and angle closure glaucoma may be associated findings. Progressive visual acuity deterioration, due to pulverulent-like cataracts, results in poor vision ranging from no light perception to 20/400. There is evidence the disease is caused by heterozygous mutation in the bestrophin-1 gene (BEST1) on chromosome 11q12. [from SNOMEDCT_US]
