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]

Variant classified as Uncertain Significance - Favor Benign. The c.315+6T>A vari ant in DIABLO has been reported in the heterozygous state in one individual with hearing loss as well as in one reportedly unaffected parent. It has also been i dentified in 0.05% (57/121370) of chromosomes by the Exome Aggregation Consortiu m (ExAC, http://exac.broadinstitute.org;dbSNP rs370571609). Although this varian t has been seen in the general population, its frequency is not high enough to r ule out a pathogenic role. This variant is located in the 5' splice region. Comp utational tools do not suggest an impact to splicing; however, this information is not predictive enough to rule out pathogenicity. In summary, while the clinic al significance of the c.315+6T>A variant is uncertain, available data suggest t hat this variant is more likely to be benign. -
