Oligogenic rare variant contributions in schizophrenia and their convergence with genes harboring de novo mutations in schizophrenia, autism, and intellectual disability: Evidence from multiplex families

Clinical and genetic heterogeneity has been documented extensively in schizophrenia, a common behavioural disorder with heritability estimates of about 80%. Common and rare de novo variant based studies have provided notable evidence for the likely involvement of a range of pathways including glutamatergic, synaptic signalling and neurodevelopment. To complement these studies, we sequenced exomes of 11 multimember affected schizophrenia families from India. Variant prioritisation performed based on their rarity (MAF
