XIAP is associated with Lymphoproliferative syndrome, X-linked, 2 in OMIM. This is an X-linked primary immune deficiency. OMIM report multiple cases of variants in the XIAP gene being associated with Lymphoproliferative syndrome, X-linked in Rigaud et al. (2006) (PMID: 17080092), Worthey et al. (2011) (PMID: 21173700), Yang et al. (2012) (PMID: 22228567), Dziadzio et al (2015) (PMID: 25943627). From these four studies 11 families were examined. Variant change effects include hemizygous frameshift, nonsense, missense and deletion mutations. The family described in Dziadzio et al (2015) includes female carriers with random X-inactivation which led to inflammatory symptoms.Created: 20 Jun 2018, 9:13 a.m.
Mode of inheritance
X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
Phenotypes
haemophagocytic lymphohistiocytosis; inflammatory bowel disease; splenomegaly

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.Created: 19 Apr 2018, 10:30 a.m.
