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

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

PP2

Missense variant in the DYRK1A gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 31 curated pathogenic missense variants (we use a threshold of 10). The gene has 88 curated benign missense variants. Gene score misZ: 3.3441 (above the threshold of 3.09). Trascript score misZ: 4.1103 (above the threshold of 3.09). GenCC associations: The gene is linked to complex neurodevelopmental disorder, DYRK1A-related intellectual disability syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.05694434).

BP6

Variant 21-37496224-C-G is Benign according to our data. Variant chr21-37496224-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 539580.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS2

High AC in GnomAdExome4 at 22 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
