Invitae | RCV000228743 | SCV000291330 | uncertain significance | Autosomal recessive polycystic kidney disease | 2015-11-26 | criteria provided, single submitter | clinical testing | The glutamine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. Furthermore, 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 these predictions have not been confirmed by published functional studies. In summary, this is a novel missense change that is not predicted to affect protein function or cause disease. However the evidence is insufficient at this time to prove that conclusively. It has been classified as a Variant of Uncertain Significance. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature. This sequence change replaces glutamic acid with glutamine at codon 1161 of the PKHD1 protein (p.Glu1161Gln). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and glutamine. |
