Genes affected

BMP1 (HGNC:1067): (bone morphogenetic protein 1) This gene encodes a protein that is capable of inducing formation of cartilage in vivo. Although other bone morphogenetic proteins are members of the TGF-beta superfamily, this gene encodes a protein that is not closely related to other known growth factors. This gene is expressed as alternatively spliced variants that share an N-terminal protease domain but differ in their C-terminal region. [provided by RefSeq, Aug 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.084337205).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000184 (28/152184) while in subpopulation AFR AF= 0.000603 (25/41460). AF 95% confidence interval is 0.000419. There are 0 homozygotes in gnomad4. There are 15 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 3 of the BMP1 protein (p.Gly3Arg). This variant is present in population databases (rs781421569, gnomAD 0.08%). This variant has not been reported in the literature in individuals affected with BMP1-related conditions. 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. 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. -
