RCV001042604 | SCV001206298 | uncertain significance | Combined immunodeficiency due to DOCK8 deficiency | 2022-06-13 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1370 of the DOCK8 protein (p.Arg1370His). This variant is present in population databases (rs753480025, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with DOCK8-related conditions. ClinVar contains an entry for this variant (Variation ID: 840574). 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. |

RCV001195229 | SCV001365536 | uncertain significance | not specified | 2019-10-18 | criteria provided, single submitter | clinical testing | The p.Arg1370His variant in DOCK8 has not been previously reported in individuals with hyper-IgE syndrome but has been identified in 7/282848 chromosomes by gnomAD (http://gnomad.broadinstitute.org). One mammal (bush baby) carries a histidine at this position despite high nearby amino acid conservation. In addition, computational prediction tools and conservation analyses suggest that this variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. ACMG/AMP Criteria applied: PM2, BP4. |
Ambry Genetics | RCV004031292 | SCV004859252 | uncertain significance | Inborn genetic diseases | 2023-12-06 | criteria provided, single submitter | clinical testing | The c.4109G>A (p.R1370H) alteration is located in exon 32 (coding exon 32) of the DOCK8 gene. This alteration results from a G to A substitution at nucleotide position 4109, causing the arginine (R) at amino acid position 1370 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
