Genes affected

BMPER (HGNC:24154): (BMP binding endothelial regulator) This gene encodes a secreted protein that interacts with, and inhibits bone morphogenetic protein (BMP) function. It has been shown to inhibit BMP2- and BMP4-dependent osteoblast differentiation and BMP-dependent differentiation of the chondrogenic cells. Mutations in this gene are associated with a lethal skeletal disorder, diaphanospondylodysostosis. [provided by RefSeq, Dec 2011]

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 6 of the BMPER protein (p.Gly6Arg). This variant is present in population databases (rs142872640, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with BMPER-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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. -
