Summary: This gene encodes a member of the CABP family of calcium binding protein characterized by four EF-hand motifs. Mutations in this gene are associated with congenital stationary night blindness type 2B. Three transcript variants encoding two different isoforms have been found for this gene.

CABP4-related retinal disease is a cone-rod system disorder with possible foveal abnormalities.
Title: Retinal findings in a patient of French ancestry with CABP4-related retinal disease.
Foveal thinning is a feature of CABP4 retinopathy. Normal autofluorescence is consistent with inner retinal dysfunction and suggests the condition could be amenable to gene therapy. Retinal dysfunction was stable throughout follow-up.
Title: Multimodal imaging in CABP4-related retinopathy.
In this study, a novel compound heterozygous mutation, c.[1A>G]; [608G>T] (p.[0?]; p.[W203L]), was identified in the LRIT3 gene of a proband. No mutations were identified in the CABP4 or GPR179 gene.

Twenty-nine CACNA1F variations were detected among 34 families in the total cohort, and a novel CABP4 variation was identified in one family.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
