Genes affected
DIABLO (HGNC:21528): (diablo IAP-binding mitochondrial protein) This gene encodes an inhibitor of apoptosis protein (IAP)-binding protein. The encoded mitochondrial protein enters the cytosol when cells undergo apoptosis, and allows activation of caspases by binding to inhibitor of apoptosis proteins. Overexpression of the encoded protein sensitizes tumor cells to apoptosis. A mutation in this gene is associated with young-adult onset of nonsyndromic deafness-64. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2013]
B3GNT4 (HGNC:15683): (UDP-GlcNAc:betaGal beta-1,3-N-acetylglucosaminyltransferase 4) This gene encodes a member of the beta-1,3-N-acetylglucosaminyltransferase protein family. The encoded enzyme is involved in the biosynthesis of poly-N-acetyllactosamine chains and prefers lacto-N-neotetraose as a substrate. It is a type II transmembrane protein.

This sequence change replaces glutamic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 214 of the DIABLO protein (p.Glu214Val). This variant is present in population databases (no rsID available, gnomAD 0.009%). This missense change has been observed in individual(s) with autosomal dominant non-syndromic deafness (PMID: 26969326). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
