Invitae RCV000647841 SCV000769644 uncertain significance Hereditary sensory and autonomic neuropathy type IIA; Pseudohypoaldosteronism type 2C 2018-12-07 criteria provided, single submitter clinical testing This sequence change replaces arginine with cysteine at codon 1957 of the WNK1 protein (p.Arg1957Cys). The arginine residue is highly conserved and there is a large physicochemical difference between arginine and cysteine. This variant is present in population databases (rs201766777, ExAC 0.08%). This variant has not been reported in the literature in individuals with WNK1-related disease. ClinVar contains an entry for this variant (Variation ID: 306612). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
