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.1372G>A (p.E458K) 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 1372, causing the glutamic acid (E) at amino acid position 458 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
