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

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.963
• PP5: Variant 8-22177929-A-G is Pathogenic according to our data. Variant chr8-22177929-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 190233.Status of the report is no_assertion_criteria_provided, 0 stars.
