Genetic Variant DYRK1B:p.Arg595Trp (chr19-39825822-G-A) – ACMG Classification: Benign (-9 pts)

Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS2

The NM_004714.3(DYRK1B):c.1783C>T(p.Arg595Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000821 in 1,608,434 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R595Q) has been classified as Likely benign.

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]
