Abstract

Many clinical phenotypes occur sporadically despite genetics contributing partly or entirely to their cause. To what extent are de novo mutations the cause of sporadic traits? Locus-specific mutation rates for genomic rearrangements appear to be two to four orders of magnitude greater than nucleotide-specific rates for base substitutions. Widespread implementation of high-resolution genome analyses to detect de novo copy-number variation may identify the cause of traits previously intractable to conventional genetic analyses.
