What is the official name of the RDH12 gene?

The official name of this gene is “retinol dehydrogenase 12 (all-trans/9-cis/11-cis).”

RDH12 is the gene's official symbol. The RDH12 gene is also known by other names, listed below.

What is the normal function of the RDH12 gene?

From Entrez GeneThis link leads to a site outside Genetics Home Reference.:

The protein encoded by this gene is an NADPH-dependent retinal reductase whose highest activity is toward 9-cis and all-trans-retinol. The encoded enzyme also plays a role in the metabolism of short-chain aldehydes but does not exhibit steroid dehydrogenase activity. Defects in this gene are a cause of Leber congenital amaurosis type 3 (LCA3). [provided by RefSeq, Jul 2008]

From UniProtThis link leads to a site outside Genetics Home Reference.:

Exhibits an oxidoreductive catalytic activity towards retinoids. Most efficient as an NADPH-dependent retinal reductase. Displays high activity toward 9-cis and all-trans-retinol. Also involved in the metabolism of short-chain aldehydes. No steroid dehydrogenase activity detected. Might be the key enzyme in the formation of 11-cis-retinal from 11-cis-retinol during regeneration of the cone visual pigments.

How are changes in the RDH12 gene related to health conditions?

Genetics Home Reference provides information about these conditions associated with changes in the RDH12 gene:
UniProtThis link leads to a site outside Genetics Home Reference. provides the following information about the RDH12 gene's known or predicted involvement in human disease.

Leber congenital amaurosis 13 (LCA13)[1]This link leads to a site outside Genetics Home Reference.: A severe dystrophy of the retina, typically becoming evident in the first years of life. Visual function is usually poor and often accompanied by nystagmus, sluggish or near-absent pupillary responses, photophobia, high hyperopia and keratoconus. Note=The disease is caused by mutations affecting the gene represented in this entry.

Retinitis pigmentosa 53 (RP53)[1]This link leads to a site outside Genetics Home Reference.: A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. Note=The disease is caused by mutations affecting the gene represented in this entry.

Entrez GeneThis link leads to a site outside Genetics Home Reference. lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the RDH12 gene.
