Variant summary

Our verdict is Benign. Variant got -10 ACMG points: 1P and 11B. PP2 BP4_Moderate BP6 BS1 BS2

The NM_001347721.2(DYRK1A):c.1762G>A(p.Ala588Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00013 in 1,613,944 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A588V) has been classified as Likely benign.

Genes affected

DYRK1A (HGNC:3091): (dual specificity tyrosine phosphorylation regulated kinase 1A) This gene encodes a member of the Dual-specificity tyrosine phosphorylation-regulated kinase (DYRK) family. This member contains a nuclear targeting signal sequence, a protein kinase domain, a leucine zipper motif, and a highly conservative 13-consecutive-histidine repeat. It catalyzes its autophosphorylation on serine/threonine and tyrosine residues. It may play a significant role in a signaling pathway regulating cell proliferation and may be involved in brain development. This gene is a homolog of Drosophila mnb (minibrain) gene and rat Dyrk gene. It is localized in the Down syndrome critical region of chromosome 21, and is considered to be a strong candidate gene for learning defects associated with Down syndrome. Alternative splicing of this gene generates several transcript variants differing from each other either in the 5' UTR or in the 3' coding region. These variants encode at least five different isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• PP2: Missense variant where missense usually causes diseases, DYRK1A
• BP4: Computational evidence support a benign effect (MetaRNN=0.1576002).
• BP6: Variant 21-37512028-G-A is Benign according to our data. Variant chr21-37512028-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 449758.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=2, Benign=1, Likely_benign=2}.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000046 (7/152072) while in subpopulation NFE AF= 0.000103 (7/68010). AF 95% confidence interval is 0.0000477. There are 0 homozygotes in gnomad4. There are 3 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd at 7 AD gene.
