What is the official name of the RLBP1 gene?

The official name of this gene is “retinaldehyde binding protein 1.”

RLBP1 is the gene's official symbol. The RLBP1 gene is also known by other names, listed below.

What is the normal function of the RLBP1 gene?

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

The protein encoded by this gene is a 36-kD water-soluble protein which carries 11-cis-retinaldehyde or 11-cis-retinal as physiologic ligands. It may be a functional component of the visual cycle. Mutations of this gene have been associated with severe rod-cone dystrophy, Bothnia dystrophy (nonsyndromic autosomal recessive retinitis pigmentosa) and retinitis punctata albescens. [provided by RefSeq, Jul 2008]

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

Soluble retinoid carrier essential the proper function of both rod and cone photoreceptors. Participates in the regeneration of active 11-cis-retinol and 11-cis-retinaldehyde, from the inactive 11-trans products of the rhodopsin photocycle and in the de novo synthesis of these retinoids from 11-trans metabolic precursors. The cycling of retinoids between photoreceptor and adjacent pigment epithelium cells is known as the 'visual cycle'.

How are changes in the RLBP1 gene related to health conditions?

Genetics Home Reference provides information about retinitis pigmentosa, which is associated with changes in the RLBP1 gene.
UniProtThis link leads to a site outside Genetics Home Reference. provides the following information about the RLBP1 gene's known or predicted involvement in human disease.

Retinitis pigmentosa autosomal recessive (ARRP)[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.

Bothnia retinal dystrophy (BRD)[2]This link leads to a site outside Genetics Home Reference.: A type of retinitis punctata albescens. Affected individuals show night blindness from early childhood with features consistent with retinitis punctata albescens and macular degeneration. Note=The disease is caused by mutations affecting the gene represented in this entry.

Rod-cone dystrophy Newfoundland (NFRCD)[3]This link leads to a site outside Genetics Home Reference.: A rod-cone dystrophy reminiscent of retinitis punctata albescens but with a substantially lower age at onset and more-rapid and distinctive progression. Rod-cone dystrophies results from initial loss of rod photoreceptors, later followed by cone photoreceptors loss. Note=The disease is caused by mutations affecting the gene represented in this entry.

Retinitis punctata albescens (RPA)[4]This link leads to a site outside Genetics Home Reference.: Rare form of stationary night blindness characterized by a delay in the regeneration of cone and rod photopigments. Note=The disease is caused by mutations affecting the gene represented in this entry.
