RCV000538613 | SCV000649463 | uncertain significance | Neuropathy, hereditary sensory and autonomic, type 2A; Pseudohypoaldosteronism type 2C | 2020-02-15 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine with glutamine at codon 2125 of the WNK1 protein (p.Arg2125Gln). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and glutamine. This variant is present in population databases (rs757825668, ExAC 0.009%). This variant has not been reported in the literature in individuals with a WNK1-related disease. 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, this variant has uncertain impact on WNK1 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
