Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_004714.3(DYRK1B):c.1777C>T(p.Arg593Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000795 in 1,609,864 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 Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R593Q) has been classified as Uncertain significance.

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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1777C>T (p.R593W) alteration is located in exon 11 (coding exon 10) of the DYRK1B gene. This alteration results from a C to T substitution at nucleotide position 1777, causing the arginine (R) at amino acid position 593 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The DYRK1B c.1777C>T variant is predicted to result in the amino acid substitution p.Arg593Trp. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0044% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
