The other three of these SNPs showed a decreased risk of melanoma: two TERT/CLPTM1L SNPs previously associated with lung cancer (rs402710, OR = 0.87; rs31489, OR = 0.89) and one ABO SNP previously associated with pancreatic cancer (rs505922, OR = 0.89). The gene discussed is ABO; the disease is familial pancreatic carcinoma.
