Mapping disease loci that underlie putative Mendelian forms of malformations of cortical development is complicated by genetic heterogeneity, small family sizes and diagnostic classifications that may not reflect molecular pathogenesis. These authors use whole-exome sequencing to identify recessive mutations in WDR62 as the cause of a wide spectrum of severe cerebral cortical malformations. WDR62's nuclear localization to germinal neuroepithelia indicates that cortical malformations can be caused by events during progenitor proliferation and neurogenesis.
