A similar conclusion is reached from studies on a small number of human pancreatic cancer samples from carriers of the Icelandic founder mutation in BRCA2, the allele BRCA2999Del5, which is 5 bp deletion in exon 9 that causes a frame‐shift leading to the expression of a very short and unstable protein product (Mikaelsdottir et al., 2004). The gene discussed is BRCA2; the disease is familial pancreatic carcinoma.
