Abstract

Context There is little information on the long-term natural history of Silver-Russell syndrome (SRS). Objective To describe the phenotypes and metabolic status in adults with SRS. Design Clinical and metabolic evaluations in adults with a molecular diagnosis of SRS. Participants Seven patients (aged 18 to 46 years; mean age, 26.9 years) were studied. Two had chromosome 7 maternal uniparental disomy, three had 11p15 loss of methylation, and two had 11p15 duplication. Setting Single tertiary university center. Main Outcome Measures Netchine-Harbison (NH) clinical score, oral glucose tolerance test, lipid profiles, bone mineral density (BMD; lumbar spine at L1 to L4 and total body), lean body mass (LBM), absolute fat mass (kg), fat mass percentage, fat mass index (FMI), and trunk/limb fat ratio were evaluated. Results The NH score declined in all but two patients during adulthood, and all patients but one displayed relative macrocephaly. Two patients were underweight, four patients had a normal body mass index, and one was obese. Two patients had glucose intolerance and hyperinsulinemia; two showed a high total cholesterol level with low high-density lipoprotein (HDL) cholesterol levels. BMD was within the normal range, whereas a high fat mass percentage, FMI, and trunk/limb fat ratio and a low LBM were found. The trunk/limb fat ratio showed an inverse relation with HDL cholesterol levels. Conclusions The diagnosis of SRS seems to be reliable in adults, although some clinical signs become less pronounced with age. Glucose, lipids, and body composition should be monitored over time.
