Children with Williams syndrome are known to be at risk for sudden cardiac death. Another test, known as fluorescent in situ hybridization [FISH], may be used to determine whether a deletion of one elastin gene on chromosome 7 is present. Williams syndrome is a rare genetic disease that affects elastin production, leading to medium and large vessel stenoses and other abnormalities.
