Stuttering like many other disorders involving complicated systems like hearing can occur due to mutations in different genes / gene combinations. These mutations cause or increase the probability of stuttering developing. This chromosome 12 finding is new as far as I know. Earlier in the year, they found mutations in genes on chromosome 3.... Genetics is making rapid progress in terms of speed and cost of analysis of, and precision of data mining on DNA. However, there is a very big unknown area from the DNA to the living brain. This process is very complex and unlikely ever be understood fully. For example, how genes form a living brain with speech abilities and how environmental influence modulate the expression of these genes.
