INTRODUCTION

Mutations that cause autosomal recessive primary microcephaly (MCPH), including MCPH1 through MCPH6, have provided insight into the normal programming that directs brain growth and defines ultimate brain size. The common denominator in these mutations is that they all manifest within neural stem and progenitor cells, decreasing their numbers at various stages of neurogenesis. Microcephalin (MCHP1) and abnormal spindlelike, microcephaly associated (MCPH5) have been the focus of most of the research. However, the recent discovery of microcephaly caused by mutation of the N-myc (also MYCN) proto-oncogene both in mice, where it was directed specifically to neural stem cells, and in the germ line in humans in Feingold syndrome has shed new light on the role of neural stem cells in brain growth. N-myc controls brain growth not only by regulating neural stem cell proliferation, but also through maintaining a . . . [Full Text of this Article]
