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 GeneticsDec 03, 2021The c.1602T>A (p.H534Q) alteration is located in exon 3 (coding exon 3) of the OCSTAMP gene. This alteration results from a T to A substitution at nucleotide position 1602, causing the histidine (H) at amino acid position 534 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
