Genes affected
BMP2 (HGNC:1069): (bone morphogenetic protein 2) This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer, which plays a role in bone and cartilage development. Duplication of a regulatory region downstream of this gene causes a form of brachydactyly characterized by a malformed index finger and second toe in human patients. [provided by RefSeq, Jul 2016]

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 11 ACMG points.
PVS1
?
Splicing variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 5.7, offset of 35, new splice context is: cgggacccgctgtcttctAGcgt. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
PM2
?
Very rare variant in population databases, with high coverage;
PP5
?
