摘要

Primary microcephaly (MCPH) is a rare autosomal recessive neurodevelopmental disorder characterized by reduced brain size and mental retardation. The reduced brain size is believed to result from asymmetric division of neuronal progenitor cells, causing reduced number of neurons. One of the six identified MCPH genes is MCPH3, which encodes cyclin-dependent kinase 5 regulatory subunit associated protein 2 (CDK5RAP2). Bond et al. have reported two different mutations, 243T-M. and IVS26-15A--G, in the CDK5RAP2 gene in two northern Pakistani microcephaly pedigrees. This landmark finding is vital for understanding the molecular mechanisms by which MCPH3 controls brain size. However, inadvertent misinterpretations of data in the report have generated a number of errors in subsequent related articles, including the generation of an incorrect mutant CDK5RAP2 mice.
