Genes affected

WNK1 (HGNC:14540): (WNK lysine deficient protein kinase 1) This gene encodes a member of the WNK subfamily of serine/threonine protein kinases. The encoded protein may be a key regulator of blood pressure by controlling the transport of sodium and chloride ions. Mutations in this gene have been associated with pseudohypoaldosteronism type II and hereditary sensory neuropathy type II. Alternatively spliced transcript variants encoding different isoforms have been described but the full-length nature of all of them has yet to be determined.[provided by RefSeq, May 2010]

This WNK1 variant (rs144292256) is rare (<0.1%) in a large population dataset (gnomAD: 6/251440 total alleles; 0.002%; no homozygotes) and has not been reported in the literature, to our knowledge. This variant has been reported in ClinVar. Of three bioinformatics tools queried, two predict that the substitution would be tolerated, while one predicts that it would be damaging. The valine residue at this position is poorly conserved across the species assessed. Due to insufficient evidence, we consider the clinical significance of c.2320G>A to be uncertain at this time. -

The c.3814G>A (p.V1272M) alteration is located in exon 12 (coding exon 12) of the WNK1 gene. This alteration results from a G to A substitution at nucleotide position 3814, causing the valine (V) at amino acid position 1272 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1272 of the WNK1 protein (p.Val1272Met). This variant is present in population databases (rs144292256, 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: 538522). 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. -
