Genes affected
OS9 (HGNC:16994): (OS9 endoplasmic reticulum lectin) This gene encodes a protein that is highly expressed in osteosarcomas. This protein binds to the hypoxia-inducible factor 1 (HIF-1), a key regulator of the hypoxic response and angiogenesis, and promotes the degradation of one of its subunits. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2023The c.667C>T (p.R223C) alteration is located in exon 6 (coding exon 6) of the OS9 gene. This alteration results from a C to T substitution at nucleotide position 667, causing the arginine (R) at amino acid position 223 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
