Variant summary
Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PM1PM2PP3_StrongPP5_Very_Strong
The NM_000441.2(SLC26A4):c.589G>A(p.Gly197Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,459,092 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G197E) has been classified as Uncertain significance.

Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Aug 02, 2021 | Variant summary: SLC26A4 c.589G>A (p.Gly197Arg) results in a non-conservative amino acid change located in the SLC26A/SulP transporter domain of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 251396 control chromosomes. c.589G>A has been reported in the literature in multiple individuals affected with SLC26A4-related conditions (e.g. Chai_2013, Luo_2020). These data indicate that the variant is very likely to be associated with disease. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Both laboratories classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. - |

not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 03, 2024 | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 197 of the SLC26A4 protein (p.Gly197Arg). This variant is present in population databases (rs111033380, gnomAD 0.006%). This missense change has been observed in individuals with SLC26A4-related conditions (PMID: 17718863, 21961810, 23385134, 28576516). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 43562). 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 with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. - |
