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.305T>C (p.V102A) alteration is located in exon 5 (coding exon 5) of the MAPK15 gene. This alteration results from a T to C substitution at nucleotide position 305, causing the valine (V) at amino acid position 102 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
