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 -14 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DYRK1A. . Gene score misZ 3.3441 (greater than the threshold 3.09). Trascript score misZ 4.1103 (greater than threshold 3.09). GenCC has associacion of gene with complex neurodevelopmental disorder, DYRK1A-related intellectual disability syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.15182665).
BP6
Variant 21-37512490-A-T is Benign according to our data. Variant chr21-37512490-A-T is described in ClinVar as [Likely_benign]. Clinvar id is 472249.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0000657 (10/152208) while in subpopulation NFE AF= 0.000132 (9/68044). AF 95% confidence interval is 0.000068. There are 0 homozygotes in gnomad4. There are 2 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 10 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
