Genes affected
XAF1 (HGNC:30932): (XIAP associated factor 1) This gene encodes a protein which binds to and counteracts the inhibitory effect of a member of the IAP (inhibitor of apoptosis) protein family. IAP proteins bind to and inhibit caspases which are activated during apoptosis. The proportion of IAPs and proteins which interfere with their activity, such as the encoded protein, affect the progress of the apoptosis signaling pathway. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2012]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2023The c.136A>G (p.M46V) alteration is located in exon 2 (coding exon 2) of the XAF1 gene. This alteration results from a A to G substitution at nucleotide position 136, causing the methionine (M) at amino acid position 46 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
