Invitae RCV000804356 SCV000944261 uncertain significance Neuropathy, hereditary sensory and autonomic, type 2A; Pseudohypoaldosteronism type 2C 2022-11-01 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 2283 of the WNK1 protein (p.His2283Arg). This variant is present in population databases (rs371469607, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with WNK1-related conditions. ClinVar contains an entry for this variant (Variation ID: 649423). 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 not expected to disrupt WNK1 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Ambry Genetics RCV002370135 SCV002667553 uncertain significance Inborn genetic diseases 2021-10-19 criteria provided, single submitter clinical testing The p.H2283R variant (also known as c.6848A>G), located in coding exon 24 of the WNK1 gene, results from an A to G substitution at nucleotide position 6848. The histidine at codon 2283 is replaced by arginine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species, and arginine is the reference amino acid in other vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
