Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 07, 2017 | This sequence change replaces arginine with lysine at codon 26 of the PRKCG protein (p.Arg26Lys). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and lysine. This variant is present in population databases (rs763526841, ExAC 0.005%). In summary, this variant has uncertain impact on PRKCG function. The available evidence is currently insufficient to determine its role 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but the clinical significance of these predictions is uncertain. A different missense substitution at this codon (p.Arg26Gly) has been reported to segregate with spinocerebellar ataxia in a large family (PMID: 22675081). This suggests that the Arg26 residue may be important for PRKCG protein function, but this prediction has not been confirmed by published functional studies. This variant has not been reported in the literature in individuals with a PRKCG-related disease. - |
