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 lysine, which is basic and polar, with arginine, which is basic and polar, at codon 94 of the STX11 protein (p.Lys94Arg). This variant is present in population databases (rs371402170, gnomAD 0.004%). 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: 576251). 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. -

The c.281A>G (p.K94R) alteration is located in exon 2 (coding exon 1) of the STX11 gene. This alteration results from a A to G substitution at nucleotide position 281, causing the lysine (K) at amino acid position 94 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
