What is the definition of Russell-Silver Dwarfism?

Russell-Silver syndrome is a growth disorder characterized by slow growth before and after birth. Babies with this condition have a low birth weight and often fail to grow and gain weight at the expected rate (failure to thrive). Head growth is normal, however, so the head may appear unusually large compared to the rest of the body. Affected children are thin and have poor appetites, and some develop recurrent episodes of low blood sugar (hypoglycemia) as a result of feeding difficulties. Adults with Russell-Silver syndrome are short; the average height for affected men is about 151 centimeters (4 feet, 11 inches) and the average height for affected women is about 140 centimeters (4 feet, 7 inches).

What are the causes of Russell-Silver Dwarfism?

The genetic causes of Russell-Silver syndrome are complex. The disorder often results from the abnormal regulation of certain genes that control growth. Research has focused on genes located in particular regions of chromosome 7 and chromosome 11.

How prevalent is Russell-Silver Dwarfism?

The exact incidence of Russell-Silver syndrome is unknown. Worldwide estimates range from 1 in 30,000 to 1 in 100,000 people.

Is Russell-Silver Dwarfism an inherited disorder?

Most cases of Russell-Silver syndrome are sporadic, which means they occur in people with no history of the disorder in their family.

Genetic Diagnosis and the Response to Recombinant Human Growth Hormone Treatment in Small for Gestational Age Children With Short Stature

Summary: This study is a multi-center, retrospective and non-interventional research. In this study, a total of 150 short children who were small for gestational age and had been treated with recombinant human growth hormone (rhGH) are selected for genetic testing. The aims of this study are to analyze the genetic etiology of SGA children with short stature, and to compare the efficacy and safety of rhGH t...
