Correlation of intestinal disaccharidase activities with the C/T-13910 variant and age

Table 1 Distribution of disaccharidase activities among Finnish adult population in relation to the C/T_-13910 genotypes

Disaccharidase	n	Genotype			Total 222	P
		C/C-13910	C/T-13910	T/T-13910
		56	83	83
Lactase		6.86 ± 0.35 (3-16)	37.8 ± 1.4 (21-99)	57.6 ± 2.4 (20-127)	37.4 ± 1.7 (3-127)	< 0.00001
Sucrase		77.2 ± 3.7 (40-172)	87.2 ± 3.8 (35-240)	83.2 ± 4,3 (24-260)	83.2 ± 2.4 (24-260)	0.14
Maltase		287.7 ± 13.2 (159-599)	342.0 ± 13.5 (161-868)	305.5 ± 14.5 (140-887)	314.6 ± 8.2 (140-887)	0.005
L/S ratio		0.09 ± 0.005 (0.03-0.2)	0.46 ± 0.02 (0.2-1.6)	0.73 ± 0.02 (0.25-1.35)	0.47 ± 0.02 (0.03-1.6)	< 0.00001

Disaccharidase activities are expressed as U/g protein, mean ± SE (range); P value based on Kruskal-Wallis test; L/S = lactase/sucrase ratio.
