Labcorp Genetics (formerly Invitae), Labcorp RCV002039306 SCV002112210 uncertain significance Gingival disorder 2021-04-29 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with FPR1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces methionine with isoleucine at codon 152 of the FPR1 protein (p.Met152Ile). The methionine residue is weakly conserved and there is a small physicochemical difference between methionine and isoleucine. 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. 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies.
