Russell-Silver syndrome is a disorder present at birth involving poor growth. One side of the body also will appear to be larger than the other.
One in 10 children with this syndrome has a problem involving chromosome 7. In other people with the syndrome, it may affect chromosome 11.
Most of the time, it occurs in people with no family history of the disease.
The estimated number of people who develop this condition varies greatly. Males and females are equally affected.
SymptomsSymptoms can include:
