In addition, it is known that the mutation in CDKN2A (also known as P16) is correlated with familial atypical mole melanoma syndrome (FAMM) (Figure 1); in STK11 (also known as LKB1), is correlated with Peutz–Jeghers syndrome (Figure 2 and Figure 3); and in PRSS1 and SPINK1, correlated with hereditary pancreatitis. Here, CDKN2A is linked to hereditary chronic pancreatitis.
