Study design: A record review study of 331 children with ASD attending CDC, Penang Hospital from September 2013 to April 2017. Results: Out of 331 children with ASD, 82.5% were males, 17.5% females, with male to female ratio of 4.7:1. Mean age at consultation was 5 years and 6 months (SD 31.68 months) with age range from 19 months to 18 years and 4 months. 85.8% were term infants with normal birth weight. History of speech regression was noted in 14.8%, epilepsy and genetic disorders in 9.4% and 5.7% respectively. Sleep problems was reported in 29.3%, dietary issues 22.1%, challenging behaviour 24.2% and ADHD 14.2%. Mean age of the father and mother at birth was 33.6 and 31.6 years respectively. Conclusion: In this study, we report a higher male to female ratio and mean age at referral with some similar rates of neurodevelopmental and medical comorbidities and relatively younger parental age with higher parental education levels. © 2019, Malaysian Medical Association.

At least half of these are thought to have a genetic etiology. Recent studies have shown that massively parallel sequencing (MPS) using a targeted gene panel is particularly suited for diagnostic testing for genetically heterogeneous conditions. We report on our experiences with using massively parallel sequencing of a targeted gene panel of 355 genes for investigating the genetic etiology of eight patients with a wide range of phenotypes including DD/ID, congenital anomalies and/or autism spectrum disorder. Targeted sequence enrichment was performed using the Agilent SureSelect Target Enrichment Kit and sequenced on the Illumina HiSeq2000 using paired-end reads. For all eight patients, 81-84% of the targeted regions achieved read depths of at least 20×, with average read depths overlapping targets ranging from 322 × to 798 ×. Causative variants were successfully identified in two of the eight patients: a nonsense mutation in the ATRX gene and a canonical splice site mutation in the L1CAM gene. In a third patient, a canonical splice site variant in the USP9X gene could likely explain all or some of her clinical phenotypes. These results confirm the value of targeted MPS for investigating DD/ID in children for diagnostic purposes. However, targeted gene MPS was less likely to provide a genetic diagnosis for children whose phenotype includes autism. © 2014 Brett et al.}, note = {cited By 20}, keywords = {Article, ATRX Gene, Autism, Autism Spectrum Disorders, Children, Clinical Article, Congenital Abnormalities, Congenital Malformation, Controlled Study, Diagnostic Test, DNA Mutational Analysis, Female, Gene, Gene Expression Profiling, Gene Mutation, Gene Targeting, Genetic Association, Genetic Association Studies, Genetic Disorder, Genetic Variability, Genetic Variation, Genetics, Genome-Wide Association Study, High Throughput Sequencing, High-Throughput Nucleotide Sequencing, Human, Intellectual Disability, Intellectual Impairment, Karyotype, L1CAM Gene, Male, Mutation, Nonsense Mutation, Nucleotide Sequence, Phenotype, Polymorphism, RNA Splice Sites, RNA Splicing, Single Nucleotide, Single Nucleotide Polymorphism}, pubstate = {published}, tppubtype = {article} } Developmental delay and/or intellectual disability (DD/ID) affects 1-3% of all children.
