Genes affected
XIAP (HGNC:592): (X-linked inhibitor of apoptosis) This gene encodes a protein that belongs to a family of apoptotic suppressor proteins. Members of this family share a conserved motif termed, baculovirus IAP repeat, which is necessary for their anti-apoptotic function. This protein functions through binding to tumor necrosis factor receptor-associated factors TRAF1 and TRAF2 and inhibits apoptosis induced by menadione, a potent inducer of free radicals, and interleukin 1-beta converting enzyme. This protein also inhibits at least two members of the caspase family of cell-death proteases, caspase-3 and caspase-7. Mutations in this gene are the cause of X-linked lymphoproliferative syndrome. Alternate splicing results in multiple transcript variants. Pseudogenes of this gene are found on chromosomes 2 and 11.[provided by RefSeq, Feb 2011]

X-linked lymphoproliferative disease due to XIAP deficiency Pathogenic:3
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jul 06, 2022 | ClinVar contains an entry for this variant (Variation ID: 523420). This premature translational stop signal has been observed in individual(s) with clinical features of X-linked lymphoproliferative syndrome 2 (PMID: 21119115, 27747465, 28936583). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Arg381*) in the XIAP gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in XIAP are known to be pathogenic (PMID: 17080092, 21119115, 25666262). For these reasons, this variant has been classified as Pathogenic. - |
