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 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.3013G>T (p.D1005Y) alteration is located in exon 17 (coding exon 17) of the AGAP2 gene. This alteration results from a G to T substitution at nucleotide position 3013, causing the aspartic acid (D) at amino acid position 1005 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
