Table 5. Summarizes the non KRAS/GNAS mutations found in precursor lesions.

Mutation type	Number of cases with mutation
VHL	8
PIK3CA, TP53	6
ATM	5
SMAD4	4
CDKN2A	3
APC, FGFR3, JAK3	2
RB1, AKT1, ARID1A, MET, FBXW7, ERBB4, PTEN, FGFR2, KIT, SMO	1

The cases with VHL gene mutation are likely to be serous cyst adenomas (SCA).
