Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the RLBP1 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: 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'. {ECO:0000269|PubMed:19846785}.
• Disease: DISEASE: Rod-cone dystrophy Newfoundland (NFRCD) [MIM:607476]: 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. {ECO:0000269|PubMed:11868161}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Retinitis punctata albescens (RPA) [MIM:136880]: A form of fleck retina disease characterized by aggregation of white flecks posteriorly in the retina, causing night blindness and delayed dark adaptation. It differs from fundus albipunctatus in being progressive and evolving to generalized atrophy of the retina. {ECO:0000269|PubMed:10102299, ECO:0000269|PubMed:11453974, ECO:0000269|PubMed:9326942}. Note=The disease is caused by mutations affecting the gene represented in this entry.
