The penetrance of schizophrenia risk in carriers of the 22q11. 2 deletion is high but
incomplete, suggesting the possibility of additional genetic defects. We performed whole
exome sequencing on two individuals with 22q11. 2 deletion, one with schizophrenia and
the other who was psychosisfree. The results revealed novel genetic variants related to
neuronal function exclusively in the person with schizophrenia (frameshift: KAT8, APOH and
SNX31; nonsense: EFCAB11 and CLVS2). This study paves the way towards a more …

This study paves the way towards a more complete understanding of variant dose and genetic architecture in schizophrenia.
