The Study of Whole Genome Sequencing in Monozygotic Twins with Autism Spectrum Disorder

Abstract

Objective: Autism spectrum disorder (ASD), the most well-known type of neurodevelopmental disorder, is a mental development disorder. Since there is no definitive biomarker for ASD, diagnosis is made based on the assessment of the patient's behavior. In addition to behavioral and social disorders, genetic factors are also important in ASD. Materials and Methods:In the study, variant analyses were performed by whole genome sequencing (WGS) method, as well as evaluating the clinical features of two monozygotic twin couples (one discordant and the other concordant).Results: According to the WGS results, thirteen high pathogenic variants were detected in twenty-nine novel candidate genes. Candidate genes include MEAF6,
