Genes affected

DOCK8 (HGNC:19191): (dedicator of cytokinesis 8) This gene encodes a member of the DOCK180 family of guanine nucleotide exchange factors. Guanine nucleotide exchange factors interact with Rho GTPases and are components of intracellular signaling networks. Mutations in this gene result in the autosomal recessive form of the hyper-IgE syndrome. Alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Jun 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.008179128).

BP6

Variant 9-340224-C-A is Benign according to our data. Variant chr9-340224-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 377797.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00198 (301/152296) while in subpopulation AFR AF = 0.00686 (285/41564). AF 95% confidence interval is 0.0062. There are 1 homozygotes in GnomAd4. There are 134 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
