Discuss the evidence for genetic factors in the etiology of ASD
What will be an ideal response?
The discovery of the fragile-X anomaly (see Chapter 5) in about 2% to 3% of children with ASD led to increased attention to this and other chromosomal defects that might be related to ASD. Some studies have found that as many as 15% to 20% of siblings of individuals with ASD also have the disorder, a number nearly twice that seen in earlier reports. New research using molecular genetics has pointed to particular areas on many different chromosomes as possible locations for susceptibility genes for ASD (Klinger et al., 2014). Susceptibility genes are causally implicated in the susceptibility to ASD but do not cause it directly on their own.
