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.1661A>G (p.N554S) alteration is located in exon 14 (coding exon 14) of the BRSK1 gene. This alteration results from a A to G substitution at nucleotide position 1661, causing the asparagine (N) at amino acid position 554 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
