[Siblings with neonatal progeroid syndrome (Wiedemann-Rautenstrauch)].

Main diagnostic criteria of neonatal progeroid syndrome are: failure to thrive and lipoatrophy, old-looking face with hydrocephalic appearance, prominent scalp veins and sparse scalp hair, large hands and feet with long fingers and toes, often neonatal teeth. NPS is usually lethal by 7 months. 5 pairs of siblings with NPS are already published. We present the second report worldwide of two siblings with NPS actually at the age of 5 and 15 years.
