Genes affected

OCSTAMP (HGNC:16116): (osteoclast stimulatory transmembrane protein) The protein encoded by this gene is orthologous to the mouse osteoclast stimulatory transmembrane protein (OCSTAMP), which is a membrane-anchored cell surface receptor that promotes nucleation of osteoclasts. The mouse protein is also involved in bone resorption and osteoclast differentiation. [provided by RefSeq, Feb 2017]

The c.1447G>A (p.D483N) alteration is located in exon 3 (coding exon 3) of the OCSTAMP gene. This alteration results from a G to A substitution at nucleotide position 1447, causing the aspartic acid (D) at amino acid position 483 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
