    Notes: Abstract The Smith-Lemli-Opitz syndrome (SLO) is an autosomal recessive disorder characterized by dysmorphic facial features with abnormal limbs and genitalia. Two forms have been recognized based on clinical course and severity: the classical SLO (type I) and the lethal acrodysgenital syndrome (type II). Type I SLO has been recently ascribed to a defect in cholesterol synthesis. Taking advantage of a series of seven patients including five type I and two type II SLO, we describe micrognathia, severe microcephaly, major ante and post natal growth retardation and feeding difficulties as consistent features in the disease. In addition, we give support to the presence of abnormal cholesterol levels in the lethal acrodysgenital syndrome but find no correlation between plasma sterol levels and the clinical severity of the disease.

In addition, we give support to the presence of abnormal cholesterol levels in the lethal acrodysgenital syndrome but find no correlation between plasma sterol levels and the clinical severity of the disease. Conclusion. The identification of the same biochemical defect in both types of Smith-Lemli-Opitz Syndrome suggests that despite major discrepancies in clinical course and severity, type I and type II SLO are probably allelic disorders.

    Notes: Abstract The authors report the ninth case of progressive familial encephalopathy in infancy, with calcification of the basal ganglia and chronic cerebrospinal fluid (CSF) lymphocytosis, as recently described by Aicardi and Goutieres. The encephalopathy appears during the first year of life with bilateral spasticity, continuing microcephaly, abnormal eye movements, and a rapid course toward a behavioral vegetative state. In every case, there is a mild lymphocytosis in the CSF and brain atrophy with calcification of the lenticular nuclei. No evidence of an infectious disease has been discovered. This syndrome constitutes a distinct type of leukodystrophy, transmitted as an autosomal recessive trait. Our case is a reminder that the presence of CSF lymphocytosis in infants, with encephalopathy and calcification of the lenticular nuclei, may be due to genetic degenerative encephalopathy.
