Summary: Involved in auditory receptor cell stereocilium organization; sensory perception of sound; and stereocilium maintenance. Acts upstream of or within inner ear auditory receptor cell differentiation. Located in stereocilium bundle. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness. Orthologous to human CLRN2 (clarin 2). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Clarin-2 gene supplementation durably preserves hearing in a model of progressive hearing loss.
Title: Clarin-2 gene supplementation durably preserves hearing in a model of progressive hearing loss.
In the differentiating hair bundles, lack of clarin-2 leads to loss of mechano-electrical transduction, followed by selective progressive loss of the transducing stereocilia.
Title: Clarin-2 is essential for hearing by maintaining stereocilia integrity and function.

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.
