Schizophrenia develops in one in every four individuals with a pathogenic 22q11.2 deletion, yet the genetic modifiers influencing the manifestation of schizophrenia in this high-risk group remain incompletely understood. Here, we identify rare tandem repeat expansions (TREs) as significant contributors to schizophrenia risk in this population. Genome sequencing of 438 unrelated individuals with 22q11.2 deletions...
