Genes affected

AGAP2 (HGNC:16921): (ArfGAP with GTPase domain, ankyrin repeat and PH domain 2) The protein encoded by this gene belongs to the centaurin gamma-like family. It mediates anti-apoptotic effects of nerve growth factor by activating nuclear phosphoinositide 3-kinase. It is overexpressed in cancer cells, and promotes cancer cell invasion. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Aug 2011]

AGAP2-AS1 (HGNC:48633): (AGAP2 antisense RNA 1) Biomarker of lung non-small cell carcinoma; malignant astrocytoma; and stomach cancer. [provided by Alliance of Genome Resources, Apr 2022]

AGAP2-AS1 links:

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]

The c.3473C>G (p.T1158R) alteration is located in exon 19 (coding exon 19) of the AGAP2 gene. This alteration results from a C to G substitution at nucleotide position 3473, causing the threonine (T) at amino acid position 1158 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
