Genes affected

APAF1 (HGNC:576): (apoptotic peptidase activating factor 1) This gene encodes a cytoplasmic protein that initiates apoptosis. This protein contains several copies of the WD-40 domain, a caspase recruitment domain (CARD), and an ATPase domain (NB-ARC). Upon binding cytochrome c and dATP, this protein forms an oligomeric apoptosome. The apoptosome binds and cleaves caspase 9 preproprotein, releasing its mature, activated form. Activated caspase 9 stimulates the subsequent caspase cascade that commits the cell to apoptosis. Alternative splicing results in several transcript variants encoding different isoforms.

Feb 14, 2023

The c.287C>T (p.S96F) alteration is located in exon 3 (coding exon 2) of the APAF1 gene. This alteration results from a C to T substitution at nucleotide position 287, causing the serine (S) at amino acid position 96 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
