Genes affected

BMPER (HGNC:24154): (BMP binding endothelial regulator) This gene encodes a secreted protein that interacts with, and inhibits bone morphogenetic protein (BMP) function. It has been shown to inhibit BMP2- and BMP4-dependent osteoblast differentiation and BMP-dependent differentiation of the chondrogenic cells. Mutations in this gene are associated with a lethal skeletal disorder, diaphanospondylodysostosis. [provided by RefSeq, Dec 2011]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 14 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 7-33905639-CTCTGGCTGA-AGACCAGAGCGGCG is Pathogenic according to our data. Variant chr7-33905639-CTCTGGCTGA-AGACCAGAGCGGCG is described in ClinVar as [Pathogenic]. Clinvar id is 30743.Status of the report is no_assertion_criteria_provided, 0 stars.
