Genes affected

MAPK15 (HGNC:24667): (mitogen-activated protein kinase 15) Enables MAP kinase activity and chromatin binding activity. Involved in several processes, including dopamine uptake; positive regulation of DNA metabolic process; and regulation of organelle organization. Located in several cellular components, including Golgi apparatus; autophagosome; and microtubule organizing center. Biomarker of breast cancer. [provided by Alliance of Genome Resources, Apr 2022]

The c.358C>A (p.Q120K) alteration is located in exon 5 (coding exon 5) of the MAPK15 gene. This alteration results from a C to A substitution at nucleotide position 358, causing the glutamine (Q) at amino acid position 120 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
