MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene localizes to the endoplasmic reticulum, where it catalyzes the esterification of all-trans-retinol into all-trans-retinyl ester. This reaction is an important step in vitamin A metabolism in the visual system. Mutations in this gene have been associated with early-onset severe retinal dystrophy and Leber congenital amaurosis 14. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2014]
PHENOTYPE: Mice homozygous for disruptions in this gene exhibit retinol homeostasis abnormalities and are more susceptible to vitamin A deficiency or display impaired vision associated with abnormal retinol metabolism. Males have testicular hypoplasia/atrophy and reduced mature sperm counts. [provided by MGI curators]
