Review of pharmacogenomics of psychiatric comorbidities in autism spectrum disorder.

Approximately 70% of individuals diagnosed with autism spectrum disorder (ASD) receive at least one psychotropic medication to treat comorbidities. However, the response to treatment with these drugs is far from satisfactory, with 30-50% of treated patients not responding adequately or developing severe and long-lasting side effects. There is strong evidence of the clinical utility of pharmacogenetics for the personalization of antipsychotic and antidepressant treatments in adult populations.

CES1 and SLC6A2 Genetic Variants As Predictors of Response To Methylphenidate in Autism Spectrum Disorders.

Purpose: Autistic spectrum disorders (ASD) children and adolescents usually present comorbidities, with 40-70% of them affected by attention deficit hyperactivity disorders (ADHD). The first option of pharmacological treatment for these patients is methylphenidate (MPH). ASD children present more side effects and poorer responses to MPH than ADHD children.
