Next Generation Sequencing Mitochondrial DNA Analysis in Autism Spectrum Disorder.

ABSTRACT: Autism is a complex genetic disorder where both de-novo and inherited genetics factors play a role. Next generation sequencing approaches have been extensively used to identify rare variants associated with autism. To date, all such studies were focused on nuclear genome; thereby leaving the role of mitochondrial DNA (mtDNA) variation in autism unexplored. Recently, analytical tools have been developed to evaluate mtDNA in whole-exome data. We have analyzed the mtDNA sequence derived from whole-exome sequencing in 10 multiplex families. In one of the families we have identified two variants of interest in MT-ND5 gene that were previously determined to impair mitochondrial function. In addition in a second family we have identified two VOIs; mtDNA variant in MT-ATP6 and nuclear DNA variant
