N=1. Even though many recessive disorders have been identified through next-generation sequencing, there is a major conceptual problem when it comes to interpreting the results of these studies. Recessive disorders are very rare and it is sometimes difficult to assess whether a given variant is truly disease-causing or simply an innocent bystander. A recent study in Nature Genetics has developed a novel concept to identify recessive disorders that rise above the overall genomic noise, finding four novel recessive disorders. In addition, the authors have enhanced their analysis by a statistical analysis of disease phenotypes.
