Genes affected

DYRK3 (HGNC:3094): (dual specificity tyrosine phosphorylation regulated kinase 3) This gene product belongs to the DYRK family of dual-specificity protein kinases that catalyze autophosphorylation on serine/threonine and tyrosine residues. The members of this family share structural similarity, however, differ in their substrate specificity, suggesting their involvement in different cellular functions. The encoded protein has been shown to autophosphorylate on tyrosine residue and catalyze phosphorylation of histones H3 and H2B in vitro. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

The c.1003G>C (p.D335H) alteration is located in exon 3 (coding exon 3) of the DYRK3 gene. This alteration results from a G to C substitution at nucleotide position 1003, causing the aspartic acid (D) at amino acid position 335 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
