Invitae RCV001903688 SCV002170843 uncertain significance Multiple congenital anomalies-hypotonia-seizures syndrome 1 2021-04-06 criteria provided, single submitter clinical testing This variant is present in population databases (rs749969084, ExAC 0.03%), including at least one homozygous and/or hemizygous individual. This sequence change replaces methionine with leucine at codon 590 of the PIGN protein (p.Met590Leu). The methionine residue is weakly conserved and there is a small physicochemical difference between methionine and leucine. This variant has not been reported in the literature in individuals with PIGN-related conditions. 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: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available").
