Russell Silver syndrome is an uncommon condition and is said to affect 1 person in fifty thousand to one hundred thousand live births. This disorder falls in the category of 200 types of dwarfism, and is also considered as one of the five types of primordial dwarfism. Till date, only some 100 reports of Russell Silver syndrome have been brought to notice. But the fact is that a lot more cases of this condition have either not been reported or detected.

The good thing is that this disorder is a type of dwarfism which can be fully cured with the help of medicines and therapies. Some treatments for this syndrome include intake of growth hormones and other medicines, proper intake of adequate calories, maintaining a good diet plan, and physical therapy.

Symptoms

Signs and symptoms of Russell Silver syndrome are more visible in children suffering from this disorder, but it tends to disappear as they slowly grow and develop. Some characteristic signs and symptoms, as per the body parts affected, include:

However, the genetic causes cannot be identified clearly. Both males and females are at equal risk to developing this disorder.

  • Some studies have connected growth abnormalities and mutations to defects in chromosome 11
  • Genomic imprinting and placental mosaicism also play a vital role in development of several signs of Russell Silver syndrome
  • Pregnancy at the age of over thirty-five years raises the risk of developing this syndrome

Treatment

Some of the treatments that can be opted to lessen the symptoms include the following:

  • Regulation of the consumption of the calories so that the affected individual may get the maximum advantage and good growth from added nutrition.
