Genes affected

STX11 (HGNC:11429): (syntaxin 11) This gene encodes a member of the syntaxin family. Syntaxins have been implicated in the targeting and fusion of intracellular transport vesicles. This family member may regulate protein transport among late endosomes and the trans-Golgi network. Mutations in this gene have been associated with familial hemophagocytic lymphohistiocytosis.

This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 18 of the STX11 protein (p.Gln18Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with STX11-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
