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]

BMP2K links:

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]

The c.2317A>G (p.N773D) alteration is located in exon 16 (coding exon 16) of the BMP2K gene. This alteration results from a A to G substitution at nucleotide position 2317, causing the asparagine (N) at amino acid position 773 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
