Detect familial hyperinsulinism (FHI)
Familial hyperinsulinism (FHI) occurs at increased frequency in individuals of Ashkenazi Jewish descent, with a carrier frequency of 1 in 66. FHI causes hypoglycemia ranging from mild to severe. Onset ranges from the newborn period to the first years of life. If left untreated, FHI may be lethal or result in irreversible neurological damage. Couples who are planning a pregnancy or who are already pregnant may decide to have testing to find out whether they are carriers and at risk of having a baby with FHI. FHI mutation analysis tests for two mutations for an 88% carrier detection rate in the Ashkenazi Jewish population.
