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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 12, 2021The c.1147C>T (p.R383C) alteration is located in exon 3 (coding exon 3) of the OCSTAMP gene. This alteration results from a C to T substitution at nucleotide position 1147, causing the arginine (R) at amino acid position 383 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
