Delayed speech and language development, and Autism

High match AUTISM, SUSCEPTIBILITY TO, 16; AUTS16

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, stereotypic, 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).For a discussion of heterogeneity of autism, see {209850}.

High match CHROMOSOME 2p16.3 DELETION SYNDROME

Deletions at 2p16.3 involving exons of NRXN1 are associated with susceptibility to autism, schizophrenia (SCZD17), developmental delay, intellectual disability, and dysmorphic features. The phenotype is highly variable and shows incomplete penetrance (summary by Dabell et al., 2013).For a phenotypic description and a discussion of genetic heterogeneity of schizophrenia, see {181500}.

High match SPECIFIC LANGUAGE IMPAIRMENT 5; SLI5

Specific language impairment-5 is characterized by a delay in early speech acquisition and is usually associated with cerebral white matter abnormalities on brain MRI. Some individuals may show disorders in communication, consistent with autism spectrum disorder, or global developmental delay, although others ultimately show normal cognitive function. Penetrance is incomplete and expressivity is variable. This type of disorder is observed most commonly among individuals of East Asian descent (summary by Wiszniewski et al., 2013).For a phenotypic description and a discussion of genetic heterogeneity of specific language impairment, see SLI1 (OMIM ).

High match AUTISM, SUSCEPTIBILITY TO, X-LINKED 6; AUTSX6

X-linked autism-6 is a neurodevelopmental disorder that affects only males. Some patients may respond favorably to carnitine supplementation (summary by Ziats et al., 2015).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, stereotypic, and ritualized patterns of interests and behavior (Bailey et al., 1996; Risch et al., 1999).
