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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJun 02, 2015Variant classified as Uncertain Significance - Favor Benign. The p.Trp7Arg varia nt in DIABLO has not been previously reported in individuals with hearing loss, but has been identified in 0.16% (43/27134) European chromosomes by the Exome Ag gregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs139511903). Computational prediction tools and conservation analysis suggest that this varia nt may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, while the clinical significance of the p. Trp7Arg variant is uncertain, its frequency in general population suggests that it is more likely to be benign. -
