Consanguinity and Heterogeneity: Cystic Fibrosis Need Not be Homogeneous in Italy.
... To the Editor: By studying the frequency of consanguinity among parents of children with cystic fibrosis (CF), Romeo et al. [1] conclude that "CF is homogeneously determined by mutations at a single gene in Italy," although the authors leave open the possibility of a very minor, second form. Such a ...
