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]

The p.P105R variant (also known as c.314C>G), located in coding exon 1 of the WNK1 gene, results from a C to G substitution at nucleotide position 314. The proline at codon 105 is replaced by arginine, an amino acid with dissimilar 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. -

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. 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. ClinVar contains an entry for this variant (Variation ID: 538505). This variant has not been reported in the literature in individuals affected with WNK1-related conditions. This variant is present in population databases (rs142165599, gnomAD 0.003%). This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 105 of the WNK1 protein (p.Pro105Arg). -
