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]

Dec 02, 2024

The c.129C>G (p.I43M) alteration is located in exon 1 (coding exon 1) of the OS9 gene. This alteration results from a C to G substitution at nucleotide position 129, causing the isoleucine (I) at amino acid position 43 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
