Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_001719.3(BMP7):c.157G>C(p.Glu53Gln) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E53K) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)
• Consequence: BMP7 NM_001719.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 5.99

Genes affected

BMP7 (HGNC:1074): (bone morphogenetic protein 7) 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, kidney and brown adipose tissue development. Additionally, this protein induces ectopic bone formation and may promote fracture healing in human patients. [provided by RefSeq, Jul 2016]
