Labcorp Genetics (formerly Invitae), Labcorp RCV000703322 SCV000832219 uncertain significance Generalized juvenile polyposis/juvenile polyposis coli 2018-05-13 criteria provided, single submitter clinical testing This sequence change replaces glycine with aspartic acid at codon 341 of the BMPR1A protein (p.Gly341Asp). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and aspartic acid. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with BMPR1A-related disease. 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, 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.
