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]

This variant has not been reported in the literature in individuals affected with FPR1-related conditions. This variant is present in population databases (rs551338523, gnomAD 0.006%). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 326 of the FPR1 protein (p.Glu326Lys). 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 1009944). -
