<i>Cleft lip and palate transmembrane 1-like</i> (<i>CLPTM1L</i>) gene rs402710 (C > T) and rs401681 (C > T) polymorphisms have been widely studied for their potential relation to cancer risk, but studies have produced conflicting results.
Several recent studies have provided evidence that rs401681 polymorphisms in intronic region of cleft lip and palate trans-membrane 1-like (CLPTM1L) gene sequence are associated with pancreatic cancer (PC) development, but a comprehensive synopsis is not available.
Recently, one genome-wide association study (GWAS), conducted exclusively among women of European ancestry, has discovered that cleft lip and palate transmembrane 1-like telomerase reverse transcriptase (CLPTM1L-TERT) rs401681 polymorphism was significantly associated with pancreatic cancer risk.
Common genetic polymorphisms on chromosome 5p15.33, including rs401681 in cleft lip and palate transmembrane 1-like gene (CLPTM1L), have been implicated in susceptibility to lung cancer through genome-wide association studies (GWAS); however, subsequent replication studies yielded controversial results.
