Detect nemaline myopathy
Nemaline myopathy occurs at increased frequency in individuals of Ashkenazi Jewish descent, with a carrier frequency of 1 in 149. Nemaline myopathy is a disorder characterized by weakness and poor muscle tone. Muscle weakness is usually most severe in the face, neck flexors, and the proximal limb muscles. In the most severe form, death often occurs in the first few years of life due to respiratory failure. 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 nemaline myopathy. Nemaline myopathy mutation analysis tests for one mutation for a 99% carrier detection rate in the Ashkenazi Jewish population.
