title: Genetic variations of insulin-like growth factor I in Italy.
abstract: Four Italian populations were examined for a HindIII RFLP associated with the human insulin-like growth factor I gene. No differences were observed among the four samples. The allele frequencies in Italy were: IGF-I HF = 0.834; IGF-I HS = 0.166. The polymorphism appears to be due to a 400-bp sequence insertion-deletion mechanism.
