Wiedemann-Rautenstrauch syndrome
is a rare disorder with a progressive course and early lethality. Severe mental and growth retardation, muscle
hypotonia
, a progeroid face, wrinkled skin, relative macrocephaly with late closure of the anterior fontanel, arachnodactyly and congenital heart defects are also typical. We report on a female infant with all the characteristic features of this syndrome after birth. Chromosomal studies on peripheral leukocytes showed a normal karyotype. In view of an abnormal lipid distribution and lipodystrophy, metabolic studies for congenital disorders of glycosylation have been performed with normal results. At the age of 2 years 6 months the progeroid signs were no longer present, and the patient had a striking improvement in her psychomotor development. As there are overlapping features in
Wiedemann-Rautenstrauch syndrome
and in mosaic polyploidy, including psychomotor retardation, reduced peripheral muscle bulk, arachnodactyly and lipodystrophy, chromosome analysis was performed in the fibroblast culture of our patient. A mosaic triploidy/tetraploidy was detected in 60% and 14% of the cells, respectively. We therefore recommend chromosome analysis of fibroblasts from patients with a neonatal presentation of progeroid features and lipodystrophy.
