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]

BMPER Gene-Disease associations (from GenCC):

• diaphanospondylodysostosis

  Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Orphanet, Labcorp Genetics (formerly Invitae), G2P
• ischio-vertebral syndrome

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
