Familial Hyperinsulinism is a rare Ashkenazi Jewish inherited disease with a carrier frequency of (1 in 66) and affects (1 in 7800) pregnancies.

Familial Hyperinsulinism: Autosomal recessive inheritance (25% if both parents are gene carriers) has been described.

Familial Hyperinsulinism is characterized by an excessive production of insulin. Symptoms can present shortly after birth, can be variable and may include lethargy, low muscle tone, irritability, poor sleeping, feeding problems and low blood sugar (hypoglycemia). Early diagnosis can help prevent learning disabilities and result in a normal life span.
