Summary: This gene encodes a ubiquitously expressed protein of unknown function. It has high levels of mRNA expression in the brain, heart, and retina and the protein co-localizes with polyglutamylated tubulin at the base of the primary cilium in human retinal pigment epithelial cells. Mutations in this gene have been associated with autosomal recessive cone-rod dystrophy (arCRD) and retinitis pigmentosa (arRP). [provided by RefSeq, Mar 2012]
Expression: Ubiquitous expression in ovary (RPKM 1.7), brain (RPKM 1.3) and 25 other tissues See more

Interactions between C8orf37 and FAM161A, Two Ciliary Proteins Essential for Photoreceptor Survival.
Title: Interactions between C8orf37 and FAM161A, Two Ciliary Proteins Essential for Photoreceptor Survival.
We conclude that C8orf37 should be added to Bardet-Biedl syndrome (BBS) screening panels as a probable rare cause of the disease and that individuals with C8orf37-related retinal dystrophy should be screened for BBS features.
Title: C8orf37 is mutated in Bardet-Biedl syndrome and constitutes a locus allelic to non-syndromic retinal dystrophies.
This report extends the genotypic spectrum of C8orf37-associated retinal dystrophies and demonstrates for the first time a genotype-phenotype correlation between an arCRD-polydactyly-association and truncating germline mutations affecting the N-terminal region of the protein.
Title: A novel C8orf37 splice mutation and genotype-phenotype correlation for cone-rod dystrophy.
This is the first functional validation and association of C8ORF37 mutations with the BBS phenotype, which identifies BBS21. The zebrafish studies hereby show that C8ORF37 variants underlie clinically diagnosed BBS-related phenotypes as well as isolated retinal degeneration
Title: Mutations in C8ORF37 cause Bardet Biedl syndrome (BBS21).
Our study identified two novel truncating mutations of the C8orf37 gene in siblings with early-onset retinal dystrophy, macular atrophy, cataracts, and high myopia.

Title: Novel C8orf37 mutations cause retinitis pigmentosa in consanguineous families of Pakistani origin.
Mutations in C8orf37 give rise to an early or adolescent-onset autosomal recessive cone rod dystrophy or retinitis pigmentosa phenotype with early macular atrophy.
Title: Clinical characteristics of rod and cone photoreceptor dystrophies in patients with mutations in the C8orf37 gene.
In a ciliary-expressed gene (C8orf37), mutations were identified that are associated with autosomal recessive cone-rod dystrophy and retinitis pigmentosa with early macular involvement.
Title: Mutations in C8orf37, encoding a ciliary protein, are associated with autosomal-recessive retinal dystrophies with early macular involvement.

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.
