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]

This sequence change affects the initiator methionine of the BMP1 mRNA. The next in-frame methionine is located at codon 155. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BMP1-related conditions. This variant disrupts a region of the BMP1 protein in which other variant(s) (p.Gly12Arg) have been determined to be pathogenic (PMID: 22482805, 24091809, 29499418). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
