These chromosomal regions contain genes [GNAQ (9q21.2), BRAF (7q34), PTEN (10q23.31), CCND1 (11q13.3), RREB1 (6p24.3), MYB (6q23.3), and CDKN2A (9p21.3)] involved in the MAPK pathway, which is consistent with the involvement of this pathway in the pathogenesis of melanoma [82,83]. The gene discussed is BRAF; the disease is melanoma.
