![]() We will also emphasize the importance of access to informed health professionals, especially in the contexts of stigma and community supports. Our purpose is to describe current trends in genetic testing for ASD, potential genetic etiologies of ASD, known genetic disorders associated with ASD, and recommendations for genetic testing in ASD. ![]() A causal genetic variant can be identified in approximately 20 to 25 of affected individuals with current clinical genetic testing, and all patients with an ASD diagnosis should be offered genetic etiologic evaluation. In the past decade, hundreds of genes have been identified that contribute to the serious deficits in. Autism spectrum disorder (ASD) is clinically and etiologically heterogeneous. ASD is highly genetically heterogeneous and may be caused by both inheritable and de novo gene variations. However, studies of ASD in the Vietnamese population are limited. Autism Spectrum Disorder (ASD) is one of the most prevalent neurodevelopmental disorders, affecting an estimated 1 in 59 children. Most importantly, children with disabilities of unknown origin should have an ongoing evaluation of potential etiologies for their symptoms (Crocker, 1987). Autism spectrum disorder (ASD) is a complex disorder with an unclear aetiology and an estimated global prevalence of 1. For example, children with ASD who have definitive etiologies may be able to access more specific resources, they may be spared long, emotionally and financially exhausting diagnostic journeys, and associated medical conditions and comorbidities can be managed proactively. Although the practices, implementation, and availability of genetic testing for ASD vary in different countries, a growing trend is the embracing of more advanced genetic testing in clinical settings 26. With these considerations in mind, it is important to recognize that genetic testing is a vital component of the diagnostic evaluation of children with ASD. Autism Spectrum Disorders (ASD) represent a group of highly inheritable disorders. In particular, ASD has a complex behavioral phenotype, and this variation reflects complex genotypes under the influence of external factors. However, ASD appear to be influenced by complex genetic and environmental factors, and evidence suggests that this is not a single gene disorder. ![]() However, evidence from family studies and linkage analyses suggests that genetic factors play a pivotal role in the etiology of ASD. At this time, no single etiology for ASD has been identified. Children with autism spectrum disorders (ASD) have unique developmental and behavioral phenotypes, and they have specific challenges with communication, social skills, and repetitive behaviors. ![]()
