For instance, Zou et al. [17] showed that the average age of pancreatitis onset in patients with molecular findings in the SPINK1, PRSS1, CTRC, and CFTR genes was 29.70±14.84 years, whereas in patients having no mutations in these genes the first clinical signs of the disease appeared at the age of 43.01±15.97 years [17]. The gene discussed is SPINK1; the disease is pancreatitis.
