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]

Pseudohypoaldosteronism type 2C;C2752089:Neuropathy, hereditary sensory and autonomic, type 2A Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 01, 2023This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 2303 of the WNK1 protein (p.Ser2303Asn). This variant is present in population databases (rs561238194, 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: 658230). 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 with a negative predictive value of 95%. 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. -
