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.

What's a GeneRIF?

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.
Title: Mutation screening of the LRIT3, CABP4, and GPR179 genes in Chinese patients with Schubert-Bornschein congenital stationary night blindness.
Twenty-nine CACNA1F variations were detected among 34 families in the total cohort, and a novel CABP4 variation was identified in one family.
Title: Clinical Characteristics, Mutation Spectrum, and Prevalence of Åland Eye Disease/Incomplete Congenital Stationary Night Blindness in Denmark.
we found a homozygous compound mutation in the CABP4 gene in 3 patients with congenital stationary night blindess 2.

This report significantly expands on the phenotype associated with calcium binding protein 4 mutations.
Title: A null mutation in CABP4 causes Leber's congenital amaurosis-like phenotype.
A novel homozygous nonsense mutation in CABP4 in two siblings resulted in a phenotype with severely reduced cone function and only negligibly reduced rod function on electroretinography and psychophysical testing.
Title: A novel homozygous nonsense mutation in CABP4 causes congenital cone-rod synaptic disorder.
it is reported for the first time that mutations in CABP4 lead to autosomal recessive congenital stationary night blindness

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.
