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.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DOCK2. . Trascript score misZ 4.9036 (greater than threshold 3.09). GenCC has associacion of gene with DOCK2 deficiency.
BP4
Computational evidence support a benign effect (MetaRNN=0.015455216).
BP6
Variant 5-169803090-A-G is Benign according to our data. Variant chr5-169803090-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 542631.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000945 (144/152328) while in subpopulation AFR AF= 0.00303 (126/41572). AF 95% confidence interval is 0.0026. There are 0 homozygotes in gnomad4. There are 71 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
