| Research Abstract |
We have collected DNA samples of 11 Japanese patients with hereditary sever microcephaly from 10 families, and analyzed for mutations in the DNA repair genes. Two patients had mutations in the MRE11A gene, and two patients had mutations in the Pericentrin gene. It was assumed that, in these patients, DNA damage accumulated in neuronal cells, and these cells were eliminated by apoptotic cell death, leading to development of microcephaly.
