摘要
A genome-wide screen was conducted for type 2 diabetes progression genes using measures of elevated fasting glucose levels as quantitative traits from the offspring enrolled in the Framingham Heart Study. We analyzed young ( 20 - 34 years) and old (greater than or equal to 35 years) subjects separately, using single-point and multipoint sibpair analysis, because of the possible differential impact of progression on the groups of interest. We observed significant linkage with change in fasting glucose levels on 1q25-32 ( p = 5.21 x 10(-8)), 3p26.3- 21.31 ( p = 1 x 10(-11)), 8q23.1- 24.13 ( p = 2.94 x 10(-6)), 9p24.1- 21.3 ( p = 7 x 10(-7)), and 18p11.31- q22.1 ( p < 10(-11)). The evidence for linkage on chromosomes 8 and 18 was consistent for the subset of study participants aged 43 through 55 years.
