Whirlin is a protein that in humans is encoded by the DFNB31 gene.[5][6][7]

In rat brain, WHRN interacts with a calmodulin-dependent serine kinase, CASK, and may be involved in the formation of scaffolding protein complexes that facilitate synaptic transmission in the central nervous system (CNS).[8] Mutations in this gene, also known as WHRN, cause autosomal recessive deafness.[7]

Model organisms

Model organisms have been used in the study of WHRN function. A conditional knockout mouse line, called Whrntm1a(EUCOMM)Wtsi[12][13] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[14][15][16]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[10][17] Twenty tests were carried out on mutant mice and two significant abnormalities were observed.[10] Whrntm1a(EUCOMM)Wtsi homozygote mice show a moderate to severe hearing loss at 14 weeks. Female homozygous mutant animals also displayed an increased thermal nociceptive threshold in a hot plate test.[10]
