Miller Dieker Syndrome

Decent Essays
Miller-Dieker lissencephaly syndrome (MDS). MDS features include classic lissencephaly (incomplete or absent gyration of the cerebrum), craniofacial dysmorphims, mental retardation and intractable epilepsy. MDS is a life-shortening disease, with death most often occurring during early childhood (Dobyns, W.B., Curry, C.J.R., Hoyme, H.E., Turlington, L., and Ledbetter, D.H.

Med. Genet 2009. 46, 825–833; Cardoso, C., Leventer, R.J., Ward, H.L., Toyo-Oka, K., Chung, J., Gross, A., Martin, C.L., Allanson, J., Pilz, D.T., Olney, A.H., et al. (2003). Refinement of a 400-kb critical region allows genotypic differentiation between isolated lissencephaly, Miller-Dieker syndrome, and other phenotypes secondary to deletions of 17p13.3. Am. J. Hum. Genet. 72, 918–930). MDS is caused by a heterozygous deletion of chromosome 17p13.3, involving several genes including PAFH1B1 and YWHAE coding for LIS1 and 14-3-3 proteins, respectively. This deletion induces malformations during cortical development (Dobyns, W.B., Stratton, R.F., Parke, J.T., Greenberg, F., Nussbaum, R.L., and Ledbetter, D.H. (1983).
