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]

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, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with FPR1-related conditions. This variant is present in population databases (rs140083445, ExAC 0.04%). This sequence change replaces alanine with threonine at codon 315 of the FPR1 protein (p.Ala315Thr). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and threonine. 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. -
