Resumen en inglés | Abstract Insulin-like growth factor (IGF-1) is an important peptide hormone involved in the reproduction and fetal developmentof mammals, and it is suggested that it may influence the human twinning rate. This study aimed to test such possible association, investigating the genetic polymorphisms IGF1(CA)n and IGFBP3rs2854744 in the population fromCandido Godoi (CG), a small city located in the South of Brazil that has a high prevalence of twin births. Acase-control study was performed comprising a total of 39 cases (representing about 40% of the mothers of twinswho were born in CG after 1995) and 214 controls (mothers of non-twin children), 97 of whom were living in CG while117 were living in Porto Alegre. DNA was extracted from blood leucocytes and genotyping was performed. Accordingto the statistical analyses, there was no significant difference in the frequencies of both studied genetic poly-morphisms when comparing case group with control group. Thus, our results pointed to a lack of association be-tweenIGF1(CA)n andIGFBP3rs2854744 polymorphisms and twin births in CG, but further investigations in otherpopulations with different characteristics must be performed to confirm the role of IGF-I in human twinning |
