Description : Autism, the prototypic pervasive developmental disorder (PDD), is usually apparent
by 3 years of age. It is characterized by a triad of limited or absent verbal communication,
a lack of reciprocal social interaction or responsiveness, and restricted, stereotypical,
and ritualized patterns of interests and behavior (Bailey et al., 1996; Risch et al.,
1999). 'Autism spectrum disorder,' sometimes referred to as ASD, is a broader phenotype
encompassing the less severe disorders Asperger syndrome (see ASPG1; 608638) and pervasive
developmental disorder, not otherwise specified (PDD-NOS). 'Broad autism phenotype'
includes individuals with some symptoms of autism, but who do not meet the full criteria
for autism or other disorders. Mental retardation coexists in approximately two-thirds
of individuals with ASD, except for Asperger syndrome, in which mental retardation
is conspicuously absent (Jones et al., 2008). Genetic studies in autism often include
family members with these less stringent diagnoses (Schellenberg et al., 2006). Levy
et al. (2009) provided a general review of autism and autism spectrum disorder, including
epidemiology, characteristics of the disorder, diagnosis, neurobiologic hypotheses
for the etiology, genetics, and treatment options. - Genetic Heterogeneity of Autism
Autism is considered to be a complex multifactorial disorder involving many genes.
Accordingly, several loci have been identified, some or all of which may contribute
to the phenotype. Included in this entry is;
Inheritance : Isolated cases; Multifactorial;
Laboratory abnormalities : Increased serum serotonin in 25%;
