Methods and Resources Genetic-linkage mapping of complex hereditary disorders to a whole-genome molecular-interaction network1 Columbia; 2 University of Chicago Common hereditary neurodevelopmental disorders such as autism, bipolar disorder, and schizophrenia are, most likely, both genetically multifactorial and heterogeneous. Because of these characteristics traditional methods for genetic analysis fail when applied to such diseases. To address the problem we propose a novel probabilistic framework that combines the standard genetic linkage formalism with whole-genome molecular-interaction data to predict pathways or networks of interacting genes that contribute to common heritable disorders. We apply the model to three large genotype-phenotype datasets, and identify a small number of highly-significant candidate genes for autism (24), bipolar disorder (21) and schizophrenia (25), and predict a number of gene targets likely to be shared among the disorders.
