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]
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 submitter | clinical testing | Ambry Genetics | Feb 13, 2024 | The c.2729T>C (p.L910P) alteration is located in exon 15 (coding exon 15) of the AGAP2 gene. This alteration results from a T to C substitution at nucleotide position 2729, causing the leucine (L) at amino acid position 910 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
