Genes affected
DOCK8 (HGNC:19191): (dedicator of cytokinesis 8) This gene encodes a member of the DOCK180 family of guanine nucleotide exchange factors. Guanine nucleotide exchange factors interact with Rho GTPases and are components of intracellular signaling networks. Mutations in this gene result in the autosomal recessive form of the hyper-IgE syndrome. Alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Jun 2010]

Autosomal recessive hyper-IgE syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 07, 2019Algorithms 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"). This variant has not been reported in the literature in individuals with DOCK8-related disease. ClinVar contains an entry for this variant (Variation ID:Ā¬ā€ 449655). This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with arginine at codon 1191 of the DOCK8 protein (p.Ser1191Arg). The serine residue is moderately conserved and there is a moderate physicochemical difference between serine and arginine. 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. -
not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingGeneDxJul 07, 2017The S1191R variant in the DOCK8 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The S1191R variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The S1191R variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. In silico analysis predicts this variant is probably damaging to the protein structure/function. However, this substitution occurs at a position that is not conserved. Therefore, we interpret S1191R as a variant of uncertain significance. -
