Invitae | RCV000690412 | SCV000818096 | uncertain significance | Alzheimer disease 4 | 2021-08-18 | criteria provided, single submitter | clinical testing | 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 disruptive. This sequence change replaces arginine with cysteine at codon 163 of the PSEN2 protein (p.Arg163Cys). The arginine residue is highly conserved and there is a large physicochemical difference between arginine and cysteine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with PSEN2-related conditions (PMID: 30279455, 30822634). ClinVar contains an entry for this variant (Variation ID: 569712). 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. |
