Urine amylase activity was measured in 142 boys and girls including unrelated twin individuals, aged 12-16 yr. Statistical analysis revealed different distribution in the group with positive protein or blood reaction. Log distribution in a homogeneous sample population was unimodal with a skewness .**GRAPHIC**. = -0.6493) and kurtosis (.beta.2 = 3.4917). Intraclass correlation coefficients of overall activities were 0.6696 (P < 0.001) in MZ twins (50 pairs) and -0.1299 (NS [not significant]) in DZ twins (22 pairs). In the rate of isozyme activity, correlation was nonsignificant. Plasma of 36 twin pairs aged 13-15 yr were similarly examined. Log distribution of overall activity was unimodal with a skewness .**GRAPHIC**. = 0.2321) and kurtosis (.beta.2 = -0.7416). Intraclass correlation coefficients of overall activity were 0.8413 (P < 0.001) in MZ twins (29 pairs) and 0.3689 (NS) in DZ twins (7 pairs). Intraclass correlation of plasma isozyme activity rate was 0.5490 (P < 0.01) in MZ twins, but not significant in DZ twins. Parent-offspring correlation of plasma overall amylase activity was 0.2848 (P < 0.05) and its mid-parent-offspring correlation was 0.3727 (P < 0.05). Heritability was 0.5298 from parent-offspring regression and 0.4408 from mid-parent-offspring regression.
