Primary immunodeficiency or monogenic inflammatory bowel disease

Gene: STX11

Comment on list classification: Changed rating of gene from Red to Green. This gene was rated as Green in v2.208 and incorrectly automatically demoted to Red in v2.209. This was due to a defect in the automatic PanelApp uploading tool when a set of publications was added to the panel with the source ‘Other’, and under certain conditions associated to previous sources listed, resulted in the rating of the gene being automatically changed when it should not have been.

Comment on list classification: Changed status from Amber to Green, there are more than 3 unrelated cases to support the phenotype Familial hemophagocytic lymphohistiocytosis-4 (FHL4) is caused by homozygous mutation in the syntaxin-11 gene (STX11; 605014) on chromosome 6q24. From OMIM Publications include: 3 unrelated Pakistani children with FHL4, each born of consanguineous parents, Muller et al. (2014) PMID: 24459464 identified a homozygous missense mutation in STX11. In a mutation analysis in a group of 63 unrelated patients with FHL of different geographic origins, Zur Stadt et al. (2006) PMID: 15703195 found 6 mutations in the STX11 gene, all in patients of Kurdish origin. Rudd et al. (2006) PMID:16582076 analyzed the STX11 gene in 34 patients with FHL from 28 unrelated families in whom PRF1 mutations had been excluded, they also suggested that STX11 mutations may be associated with secondary malignancies as three of the children experienced more than 1 year in remission without specific treatment, which the authors stated was very uncommon in this disease. Two of the children developed severe psychomotor retardation, one developed acute myelodysplastic syndrome, and one developed acute myelogenous leukemia. They noted that a total of 13 individuals from 8 Turkish families had been shown to carry STX11 mutations

from OMIM: Familial hemophagocytic lymphohistiocytosis is an autosomal recessive disease that presents as a severe hyperinflammatory syndrome with activated macrophages and T lymphocytes. Zur Stadt et al. (2005) PMID: 15703195 mapped one form of FHL (FHL4; 603552) to chromosome 6q24 by homozygosity mapping. They identified a 5-bp deletion (605014.0001), a large genomic deletion (605014.0002), and a nonsense mutation (Q268X; 605014.0003) in the STX11 gene, which maps to the 6q24 region.

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.
