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]

The c.494C>T (p.A165V) alteration is located in exon 4 (coding exon 4) of the BMP2K gene. This alteration results from a C to T substitution at nucleotide position 494, causing the alanine (A) at amino acid position 165 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
