RCV001089556 | SCV001244793 | uncertain significance | Autosomal dominant nonsyndromic hearing loss 12 | 2017-12-28 | criteria provided, single submitter | clinical testing | A heterozygous missense variant NM_005422.2(TECTA):c.1796G>C, has been identified in exon 8of 23 of the TECTA gene.This substitution is predicted to create a minor amino acid change from serine to threonine at amino acid position 599, NP_005413.2(TECTA):p.(Ser599Thr).The serine at this position has low conservation (100 vertebrates, UCSC). In silico software predicts this variant to be benign (Polyphen, SIFT, CADD, Mutation Taster). It is situated in a trypsin inhibitor-like, cystein rich domain.This variant has not been previously reported, but has been observed in a population database at a frequency of 0.0004% (ExAC, GnomAD). Subsequent analysis of parental samples indicated this variant was maternally inherited. Based on current information, this variant has been classified as a VUS with LOW clinical significance. |
