Labcorp Genetics (formerly Invitae), Labcorp RCV003062641 SCV003442340 uncertain significance Alzheimer disease 3; Frontotemporal dementia; Pick disease; Acne inversa, familial, 3 2022-07-01 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 131 of the PSEN1 protein (p.His131Arg). 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. Experimental studies have shown that this missense change affects PSEN1 function (PMID: 27930341, 32087291). 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. This missense change has been observed in individuals with early-onset Alzheimer’s disease (PMID: 23638752, 33188256). This variant is not present in population databases (gnomAD no frequency).
