RCV000221030 | SCV000271212 | likely pathogenic | Rare genetic deafness | 2016-01-14 | criteria provided, single submitter | clinical testing | The deletion of exons 7-9 in DFNA5 has been previously reported in one individua l with hearing loss and segregated with disease in two affected family members. It was not observed in large population studies. This variant leads to a loss of exons 7-9 of the DFNA5 gene and is predicted to result in a truncated or absent protein. To date, all variants in DFNA5 reported to cause hearing loss result i n exon 8 skipping (Yu 2003, Bischoff 2004, Van Laer 2005, Cheng 2007, Park 2010, Nishio 2014); however, the mechanism is unknown. In summary, although additiona l studies are required to fully establish its clinical significance, this varian t is likely pathogenic. It should be noted that exact breakpoints of the detecte d deletion could not be determined due to limitations of the testing methodology . |
