Hi, I am not a geneticist, but the consensus seems to be that there is no single stuttering gene. It is very likely that different combinations of genes make people vunerable to developing persistent development stuttering. For example, genetics research has been conducted on two families: one in Pakistan, and one in Cameroon. Most members of the two families are stuttering. The studies reveal strong signals on several chromosomes (packages of genes) but they were different for each family. Also, research from other disorders like deafness (I think) found more than 80 different genes correlated to deafness. Thus, I just wanted to say that the picture is complicated. Dr Drayna, who has written a genetics artcile for this conference, will be able to answer your more detailed questions.
