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.686A>G (p.Y229C) alteration is located in exon 6 (coding exon 6) of the BMP2K gene. This alteration results from a A to G substitution at nucleotide position 686, causing the tyrosine (Y) at amino acid position 229 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
