SRS or Russell-Silver syndrome (RSS) as it is sometimes called, is a rare genetic growth disorder. Children are generally born smaller than expected with distinct facial features. Sometimes different parts of the body will grow at different rates. Children with SRS will not catch-up to normal height in the first 2 years of life, and will need treatment early on.
SRS is a genetic growth disorder caused by errors in different parts of some genes. It was originally documented in the 1950s by ‘Silver’ and ‘Russell’, who reported a number of children with low birth weights and short stature.
As many parts of the gene can be affected, there may be a number of symptoms. These can include low birth weight and short stature, distinct facial features, and sometimes a curvature in the child’s little finger (5th finger).
Diagnosis of SRS can be difficult due to the varied features and symptoms. The healthcare professional will look at the physical symptoms as well as performing follow-up measurements of growth. Some of the distinct facial features may become less obvious with age, so it is vital to diagnose early so that an accurate diagnosis can be completed. Genetic testing may also help with the diagnosis.
