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.

Familial hemophagocytic lymphohistiocytosis 4 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 16, 2022This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 9 of the STX11 protein (p.Leu9Pro). This variant is present in population databases (rs34470310, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with STX11-related conditions. ClinVar contains an entry for this variant (Variation ID: 643041). 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. -
