Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2 BP7

The NM_203447.4(DOCK8):c.3010C>A(p.Arg1004=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. R1004R) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: DOCK8 NM_203447.4 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.775

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

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP7: Synonymous conserved (PhyloP=0.775 with no splicing effect.
