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 Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.56).
• BP6: Variant 19-39825781-G-A is Benign according to our data. Variant chr19-39825781-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 3354130.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP7: Synonymous conserved (PhyloP=2.68 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 24 AD gene.
