Additionally, the same study analyzed the presence of Cav3.1 and Cav3.2 isoforms in the four main primary cutaneous melanoma subtypes (superficial spreading malignant melanoma (SSMM), nodular melanoma (NM), acral lentiginous melanoma (ALM), and lentigo maligna melanoma (LMM)). The gene discussed is CACNA1G; the disease is acral lentiginous melanoma.
