Until recently, speech and language disorders
have been viewed as complex disorders produced by multiple-gene
interaction. Participant samples selected for genetics studies consisted
of affected children, their siblings, and, in some cases, the parents or even a multigenerational set of relatives; most samples represented many different families.
A new approach to studying the genetics of speech and language
disorders is to study the disorder within individual families. If there
are distinct subtypes of genetic etiology, this approach is more likely
to capture causal genes and is more feasible now than in the past, given
new technology such as high-efficiency (“next-generation”) sequencing
of parts of or even the entire genome. Follow this link to learn more!
