Genes affected

API5 (HGNC:594): (apoptosis inhibitor 5) This gene encodes an apoptosis inhibitory protein whose expression prevents apoptosis after growth factor deprivation. This protein suppresses the transcription factor E2F1-induced apoptosis and also interacts with, and negatively regulates Acinus, a nuclear factor involved in apoptotic DNA fragmentation. Its depletion enhances the cytotoxic action of the chemotherapeutic drugs. Multiple alternatively spliced transcript variants encoding different isoforms have been identified.

The c.1388G>A (p.G463D) alteration is located in exon 13 (coding exon 13) of the API5 gene. This alteration results from a G to A substitution at nucleotide position 1388, causing the glycine (G) at amino acid position 463 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
