\begin{abstract}
Hello reddit! I'm Shelly Jo Kraft, an Assistant Professor at Wayne State
University. My research focuses on the biological and behavioral
genetics of stuttering. I also work on studies that investigate
neuro-anatomical and functional features of people who stutter, auditory
feedback mechanisms of speech control, and new genetic analysis
techniques for modeling epigenetic complexity. Clinically, I am
interested in the relationship between cognition, temperament, and
stuttering severity. Stuttering is a developmental speech disorder that
affects 1\% of the adult population, and 5-6\% of the child population
world-wide. To date, the genes responsible for the disorder have yet to
be conclusively identified in the general population. Only a small
number of studies have been conducted on the genetic susceptibility of
this disorder. I am leading a new study, to discover more about the
genes and biological mechanisms that increase risk of stuttering. To
identify the these genes, we are working to collect as many saliva
samples as possible from people around the world who stutter. I can
answer any questions you might have about developmental stuttering, how
we know it is genetic, and about participating in the study. If you want
to participate, the first step is to read and fill out these forms about
the study. Next, we will schedule a short phone call interview with me
or another qualified speech and language pathologist. After that, we
will mail you a saliva collection kit and a very brief questionnaire.
Our understanding of the cause of stuttering will potentially provide a
foundation for new treatment approaches. Please join me in this
international effort! Thank you so much for your excellent questions! I
really appreciated your enthusiasm for this exciting area of research,
and your support for our study. I would also like to thank everyone who
shared a personal anecdote of their experience as a person who stutters.
I will try to come back later tonight to check in and answer any
additional questions that come in. Thanks again!!
