BACKGROUND GABRB3 is a position candidate gene at chromosome 15q12 that has been implicated in the neurobiology of autism spectrum disorders (ASD). The aim of this study was to examine the genetic association of GABRB3 with ASD. METHODS The sample consisted of 356 patients with clinical diagnosis of ASD according to the DSM-IV diagnostic criteria and(More)
Autism spectrum disorders (ASD) are childhood-onset neurodevelopmental disorders characterized by verbal communication impairments, social reciprocity deficits, and the presence of restricted interests and stereotyped behaviors. Genetic factors contribute to the incidence of ASD evidently. However, the genetic spectrum of ASD is highly heterogeneous.(More)
BACKGROUND Comparative gene expression profiling analysis is useful in discovering differentially expressed genes associated with various diseases, including mental disorders. Autism spectrum disorders (ASD) are a group of complex childhood-onset neurodevelopmental and genetic disorders characterized by deficits in language development and verbal(More)
BACKGROUND We recently reported a terminal deletion of approximately 2.4 Mb at chromosome 8p23.2-pter in a boy with autism. The deleted region contained the DLGAP2 gene that encodes the neuronal post-synaptic density protein, discs, large (Drosophila) homolog-associated protein 2. The study aimed to investigate whether DLGAP2 is genetically associated with(More)
Previous evidence suggests that language function is modulated by genetic variants on chromosome 7q31-36. However, it is unclear whether this region harbors loci that contribute to speech delay in autism. We previously reported that the WNT2 gene located on 7q31 was associated with the risk of autism. Additionally, two other genes on 7q31-36, FOXP2 and the(More)
Autism is a complex neurodevelopmental disorder with high heritability. Despite different approaches worldwide to identify susceptibility loci or genes for autism spectrum disorders (ASDs), no consistent result has been reported. CNS patterning genes have been recognized as candidate genes for autism based on neuroimage and neuropathology evidence. This(More)
Autism spectrum disorders (ASDs), characterized by different degree of impaired social interaction, communication deficits, and restricted interests, are a group of complex neurodevelopmental disorders that include autistic disorder (autism), Asperger's disorder (AD), and pervasive developmental disorder not otherwise specified (American Psychiatric(More)
AIM To investigate the effects of age, gender, prenatal/perinatal factors, and maternal psychological distress on childhood emotional/behavioral problems, and the gender difference in the patterns of comorbid emotional/behavioral problems. METHODS The sample included 1391 children aged 4-9 in Taipei using a multi-stage sampling method. Their mothers(More)
OBJECTIVE The aim of the present study was to examine changes of attention-deficit-hyperactivity disorder (ADHD) symptoms and psychiatric comorbidities at adolescence, and mother-child agreement on reports of ADHD symptoms among children with ADHD as compared to unaffected controls. METHODS The participants included 93 patients (male, 82.8%) aged 11-16,(More)
BACKGROUND Autism spectrum disorder (ASD) is an early-onset neurodevelopmental disorder with complex genetic underpinning in its etiology. Copy number variations (CNVs) as one of the genetic factors associated with ASD have been addressed in recent genome-wide association studies (GWAS). However, the significance of CNV has not been well investigated in(More)
