- Lipoamide Dehydrogenase (LAD)
Detect dihydrolipoamide dehydrogenase deficiency (DLD)
Dihydrolipoamide dehydrogenase deficiency (DLD), also known as lipoamide dehydrogenase deficiency (LAD), is an autosomal-recessive disorder that occurs at an increased frequency in individuals of Ashkenazi Jewish descent, with a carrier frequency of 1 in 96. DLD presents as persistent lactic acidosis with recurrent episodes of vomiting and abdominal pain. There is progressive neurological impairment, hepatomegaly, cortical blindness, stupor, and coma. Mortality is high. 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 DLD. DLD mutation analysis tests for two mutations for a 95% carrier detection rate in the Ashkenazi Jewish population.
