Some individuals with autism excel in visual skills, music, math, and art. Autism can be associated with intellectual disability, difficulties in motor coordination and attention and physical health issues such as sleep and gastrointestinal disturbances. The reported incidence of autism spec-trum disorders has increased dramatically over the past two decades. These disorders are characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors. The autism spectrum disorders are a collective of conditions that have in common impaired socialization and communication in association with stereotypic behaviors. What is Autism Spectrum Disorder?Īutism spectrum disorder is a general term that refers to a group of complex disorders of brain development. Genetic testing and autism spectrum disorder Your child or another family member has syndromic ASD A family member has an ASD-related genetic change found through genetic testing or Multiple family members have ASD. Since then, scientists have been racking up potential genetic culprits in autism, a process that DNA-decoding technologies have accelerated in the past decade. The causes of autism are not completely understood however an increasing number of genetic factors have been identified. Researchers have known that genes contribute to autism since the 1970s, when a team found that identical twins often share the condition. Patients and their families are often referred to us to evaluate for a possible inherited cause of autism. Certain gene changes or mutations can cause autism by themselves. The genetic approach to ASD continues to be challenging for physicians in countries such as Mexico due to high costs, lack of reimbursement and. Clinical genetic testing included G-banded karyotype, fragile X testing, and chromosomal microarray (CMA) to test for submicroscopic genomic deletions and duplications. Knowledge of familial risk factors for developing the disorder can be extremely beneficial both to the affected individual and his or her family. We use a comprehensive approach for patients with autism spectrum disorders, including the most advanced genetic testing, to try and identify an underlying cause of autism in each affected person.
