The main feature of Russell-Silver syndrome (RSS) is low birth weight followed by continued growth delays after birth. Individuals with RSS typically have proportionately short stature and normal head circumference. Certain characteristic facial features may also be present (triangular face, down-turned angles of the mouth, prominent forehead, prominent nasal bridge and a small jaw). Other variable features may be seen in children with RSS (see For More Information). Some individuals with RSS will have many of the possible characteristics associated with RSS while others will have very few.
