title: The prevalence of type II diabetes mellitus is haptoglobin phenotype-independent.
abstract: Haptoglobin (Hp) phenotype distribution and the association between Hp polymorphism and type II diabetes mellitus was investigated in a Jordanian sample population consisting of 618 nondiabetics and 265 diabetics. In nondiabetics, Hp 2-2 was the most predominant type occurring at a frequency of 0.529 followed by Hp 2-1 occurring at a frequency of 0.387. In diabetics, the Hp 2-2 frequency was 0.540 while that of Hp 2-1 was 0.381. No statistically significant variation was detected in Hp type distribution between the two groups. The Hp2 allele occurred at a frequency of 0.722 in nondiabetics and 0.730 in diabetics. In both groups, the Hp type distribution was in agreement with the Hardy-Weinberg equilibrium calculations. These results suggest that type II diabetes mellitus is Hp phenotype-independent.
