Figure 2From: A novel mutation in STK11 gene is associated with Peutz-Jeghers Syndrome in Chinese patients The germline nonsense mutation of the STK11 gene. Arrows indicate the position of the mutation and the underlines highlight the codon containing the mutation. The wide-type sequence CAG (glutamine) is altered to the mutant sequence TAG (stop) at codon 302, which leads to truncation of the STK11 protein.Back to article page
