Genes affected

BMP2K (HGNC:18041): (BMP2 inducible kinase) This gene is the human homolog of mouse BMP-2-inducible kinase. Bone morphogenic proteins (BMPs) play a key role in skeletal development and patterning. Expression of the mouse gene is increased during BMP-2 induced differentiation and the gene product is a putative serine/threonine protein kinase containing a nuclear localization signal. Therefore, the protein encoded by this human homolog is thought to be a protein kinase with a putative regulatory role in attenuating the program of osteoblast differentiation. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

PAQR3 (HGNC:30130): (progestin and adipoQ receptor family member 3) This gene encodes a seven-transmembrane protein localized in the Golgi apparatus in mammalian cells. The encoded protein belongs to the progestin and adipoQ receptor (PAQR) family. This protein functions as a tumor suppressor by inhibiting the Raf/MEK/ERK signaling cascade. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2017]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
