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 was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.007919282).

BP6

Variant 5-169654449-G-C is Benign according to our data. Variant chr5-169654449-G-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 542623.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00216 (329/152336) while in subpopulation AFR AF = 0.00488 (203/41580). AF 95% confidence interval is 0.00433. There are 3 homozygotes in GnomAd4. There are 156 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 3 AR gene
