Genes affected

CASP3 (HGNC:1504): (caspase 3) The protein encoded by this gene is a cysteine-aspartic acid protease that plays a central role in the execution-phase of cell apoptosis. The encoded protein cleaves and inactivates poly(ADP-ribose) polymerase while it cleaves and activates sterol regulatory element binding proteins as well as caspases 6, 7, and 9. This protein itself is processed by caspases 8, 9, and 10. It is the predominant caspase involved in the cleavage of amyloid-beta 4A precursor protein, which is associated with neuronal death in Alzheimer's disease. [provided by RefSeq, Aug 2017]

Feb 05, 2024

The c.760G>A (p.A254T) alteration is located in exon 8 (coding exon 6) of the CASP3 gene. This alteration results from a G to A substitution at nucleotide position 760, causing the alanine (A) at amino acid position 254 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
