Genes affected

DYRK1B (HGNC:3092): (dual specificity tyrosine phosphorylation regulated kinase 1B) This gene encodes a member of a family of nuclear-localized protein kinases. The encoded protein participates in the regulation of the cell cycle. Expression of this gene may be altered in tumor cells, and mutations in this gene were found to cause abdominal obesity-metabolic syndrome 3. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.61).
• BP6: Variant 19-39825778-A-C is Benign according to our data. Variant chr19-39825778-A-C is described in ClinVar as [Likely_benign]. Clinvar id is 3044298.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP7: Synonymous conserved (PhyloP=-0.385 with no splicing effect.
