Description

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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has been observed in individual(s) with clinical features of Bartter syndrome (Invitae). This variant is present in population databases (rs138120505, ExAC 0.006%). This sequence change replaces arginine with serine at codon 188 of the KCNJ1 protein (p.Arg188Ser). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and serine.
