Genes affected

AGFG2 (HGNC:5177): (ArfGAP with FG repeats 2) This gene is a member of the HIV-1 Rev binding protein (HRB) family and encodes a protein with one Arf-GAP zinc finger domain, several phe-gly (FG) motifs, and four asn-pro-phe (NPF) motifs. This protein interacts with Eps15 homology (EH) domains and plays a role in the Rev export pathway, which mediates the nucleocytoplasmic transfer of proteins and RNAs. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Feb 2013]

The c.973G>A (p.V325M) alteration is located in exon 7 (coding exon 7) of the AGFG2 gene. This alteration results from a G to A substitution at nucleotide position 973, causing the valine (V) at amino acid position 325 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
