Variant summary
Our verdict is Pathogenic. Variant got 20 ACMG points: 20P and 0B. PS1PM2PM5PP3_StrongPP5_Very_Strong
The NM_000441.2(SLC26A4):c.1371C>A(p.Asn457Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000411 in 1,461,340 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N457D) has been classified as Pathogenic.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 06, 2023 | This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 457 of the SLC26A4 protein (p.Asn457Lys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Pendred syndrome and deafness (PMID: 12676893, 20597900). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 550172). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt SLC26A4 protein function. Experimental studies have shown that this missense change affects SLC26A4 function (PMID: 31599023). For these reasons, this variant has been classified as Pathogenic. - |
