Genes affected
ANKS4B (HGNC:26795): (ankyrin repeat and sterile alpha motif domain containing 4B) Involved in brush border assembly; cellular protein-containing complex assembly; and protein localization to microvillus. Located in brush border and microvillus. [provided by Alliance of Genome Resources, Apr 2022]
CRYM (HGNC:2418): (crystallin mu) Crystallins are separated into two classes: taxon-specific and ubiquitous. The former class is also called phylogenetically-restricted crystallins. The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency and refractive index of the lens. This gene encodes a taxon-specific crystallin protein that binds NADPH and has sequence similarity to bacterial ornithine cyclodeaminases. The encoded protein does not perform a structural role in lens tissue, and instead it binds thyroid hormone for possible regulatory or developmental roles. Mutations in this gene have been associated with autosomal dominant non-syndromic deafness. [provided by RefSeq, Sep 2014]
