Newest Methods for Detecting Structural Variations

A substantial amount of structural variation in the human genome remains uninvestigated due to the limitations of existing technologies, the presence of repetitive sequences, and the complexity of a diploid genome. New technologies have been developed, increasing resolution and appreciation of structural variation and how it affects human diversity and disease. The genetic etiology of most patients with complex disorders such as neurodegenerative brain diseases is not yet elucidated, complicating disease diagnosis, genetic counseling, and understanding of underlying pathological mechanisms needed to develop therapeutic interventions. Here, we focus on innovative progress and opportunities provided by the newest methods such as linked read sequencing, strand-specific sequencing, and long-read sequencing. Finally, we describe a strategy for generating a comprehensive catalog of structural variations across populations.
