Distribution of hMLH1 protein expression by DNA microsatellite status in dysplastic samples from mixed polyps and serrated adenomas

	No of dysplastic foci by DNA microsatellite status
hMLH1 protein	MSS	MSI-L	MSI-H	NA^1-150
Present	2	3	0	5^1-160
Lost	4	0	4	17

↵1-150 NA, not available (microsatellite instability (MSI) status not tested); MSI-H, MSI-high; MSI-L, MSI-low; MSS, microsatellite stable.
↵1-160 Four traditional adenomas from patient No 4 retained hMLH1 expression but are not included.
