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]

Collection Method: clinical testing

The c.497T>C (p.V166A) alteration is located in exon 4 (coding exon 4) of the BMP2K gene. This alteration results from a T to C substitution at nucleotide position 497, causing the valine (V) at amino acid position 166 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
