F. Gurrieri et al., Pervasive developmental disorder and epilepsy due to maternally derived duplication of 15q11-q13, NEUROLOGY, 52(8), 1999, pp. 1694-1697
Duplications of chromosome 15 have been reported in individuals with atypic
al autism, varying degrees of mental retardation, and epilepsy. The authors
report the molecular analysis, neurophysiologic, and clinical evaluation o
f a 12-year-old boy with atypical autism and epilepsy due to a maternally d
erived 15q11-q13 duplication. Their findings suggest that this chromosomal
region harbors genes for autism and possibly for partial epilepsy that may
act in a dose-dependent manner.
