Abstract Background Reduced growth during infancy is associated with adult insulin resistance. In a UK Caucasian cohort the microsatellite polymorphism in the growth hormone-chorionic somatomammotropin hormone gene cluster was recently associated with increases in adult fasting insulin of approximately 23 pmol l for TT homozygote males compared to D1D1 or D2D2 homozygotes P and n 206 and 92 respectively but not for females. TT males additionally had a 547-g lower weight at 1 year n 270 P than D2D2 males. We sought to replicate these data in healthy UK Caucasian subjects. We genotyped 1396 subjects fathers .
