We report the case of a 6-year-2-month-old female affected by trisomy
12p syndrome. Seizures were typical myoclonic absences from both the c
linical and EEG points of view. Our patient and other sporadic reports
in the literature seem to support the hypothesis that, at least in so
me cases, myoclonic absences can be a direct or indirect effect of a c
hromosomopathy. (C) 1998 Elsevier Science B.V.
