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 glutamic acid with alanine at codon 7 of the STX11 protein (p.Glu7Ala). The glutamic acid residue is moderately conserved and there is a moderate physicochemical difference between glutamic acid and alanine. This variant is present in population databases (rs201888313, ExAC 0.01%). 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. -
