Genes affected

BRSK1 (HGNC:18994): (BR serine/threonine kinase 1) Enables magnesium ion binding activity; protein serine/threonine kinase activity; and tau-protein kinase activity. Involved in mitotic G2 DNA damage checkpoint signaling and protein phosphorylation. Acts upstream of or within G2/M transition of mitotic cell cycle; peptidyl-serine phosphorylation; and response to UV. Located in cell junction; cytoplasm; and nucleoplasm.

The c.1639G>A (p.A547T) alteration is located in exon 14 (coding exon 14) of the BRSK1 gene. This alteration results from a G to A substitution at nucleotide position 1639, causing the alanine (A) at amino acid position 547 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
