RCV000214219 | SCV000271270 | likely pathogenic | Rare genetic deafness | 2015-03-04 | criteria provided, single submitter | clinical testing | The c.6163-2A>T variant in TECTA has not been previously reported in individuals with hearing loss and was absent from large population studies. This variant oc curs in the invariant region (+/- 1/2) of the splice consensus sequence and is p redicted to cause altered splicing leading to an abnormal or absent protein. Var iants in TECTA have been associated with both autosomal recessive and autosomal dominant nonsyndromic hearing loss, with recessive variants primarily loss of fu nction and dominant typically missense variants. In summary, although additional studies are required to fully establish its clinical significance, this variant is likely pathogenic for autosomal recessive nonsyndromic hearing loss based on its predicted impact to splicing. |

RCV002519623 | SCV003282663 | likely pathogenic | not provided | 2022-05-15 | criteria provided, single submitter | clinical testing | This sequence change affects an acceptor splice site in intron 20 of the TECTA gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in TECTA are known to be pathogenic (PMID: 11087000, 12746400, 17431902, 24130743). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TECTA-related conditions. ClinVar contains an entry for this variant (Variation ID: 228295). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. |
