Carcinomas with residual adenoma showing a GNAS mutation in one or both portions, with KRAS mutation status and mucin status

Tumor #	Adenomatous part		Carcinomatous part
	GNAS mut	KRAS	GNAS mut	Mucin	KRAS
1	R201C	Mutated	R201C	<50%*	Mutated
2	R201H	Wild	WILD	<50%	Wild
3	R201H	Wild	WILD	<50%	Mutated
4	R201H/R201S	Wild	R201H	<50%	Mutated
5	R201H	Mutated	WILD	<50%	Mutated
6	R201H	Mutated	WILD	<50%	Mutated
7	WILD	Mutated	R201H	>50%	Mutated

^*Carcinomas with >50% mucin meet WHO criteria for mucinous adenocarcinoma.
