Genes affected
DOCK2 (HGNC:2988): (dedicator of cytokinesis 2) The protein encoded by this gene belongs to the CDM protein family. It is specifically expressed in hematopoietic cells and is predominantly expressed in peripheral blood leukocytes. The protein is involved in remodeling of the actin cytoskeleton required for lymphocyte migration in response to chemokine signaling. It activates members of the Rho family of GTPases, for example RAC1 and RAC2, by acting as a guanine nucleotide exchange factor (GEF) to exchange bound GDP for free GTP. Mutations in this gene result in immunodeficiency 40 (IMD40), a combined form of immunodeficiency that affects T cell number and function, also with variable defects in B cell and NK cell function.

DOCK2 deficiency Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jul 23, 2022 | This sequence change replaces aspartic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 1454 of the DOCK2 protein (p.Asp1454Ala). This variant is present in population databases (rs779110995, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with DOCK2-related conditions. ClinVar contains an entry for this variant (Variation ID: 580078). 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. - |
