Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.
The NM_203447.4(DOCK8):c.3573C>G(p.Ser1191Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000496 in 1,614,082 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. S1191S) has been classified as Likely benign.

The 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. -
Uncertain:1
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. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with DOCK8-related disease. ClinVar contains an entry for this variant (Variation ID: 449655). 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. -
