Genes affected

FPR1 (HGNC:3826): (formyl peptide receptor 1) This gene encodes a G protein-coupled receptor of mammalian phagocytic cells that is a member of the G-protein coupled receptor 1 family. The protein mediates the response of phagocytic cells to invasion of the host by microorganisms and is important in host defense and inflammation.[provided by RefSeq, Jul 2010]

Feb 03, 2023

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 137 of the FPR1 protein (p.Arg137Cys). This variant is present in population databases (rs139132326, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with FPR1-related conditions. ClinVar contains an entry for this variant (Variation ID: 575041). 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. 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. -
