CDKN2A and familial pancreatic carcinoma: The standardised incidence ratio was 19.1 (95% CI 8.3 to 33.6) and the cumulative PDAC incidence at age 75 years (lifetime risk) was 19% (95% CI 7.5% to 30.1%).<h4>Conclusions</h4>Our results support the notion that pathogenic <i>CDKN2A</i> variants affecting the p16INK4a protein, including c.67G>C, are associated with increased PDAC risk and carriers of such variants should be offered pancreatic cancer surveillance.
