RETT Syndrome Mutation

Clinical Info

Sequence analysis of the entire amino acid coding region (exons 1-4) and splice junction sites of the MECP2 gene will detect disease causing variants in approximately 80% Of individuals with classic Rett Syndrome. This test will establish a clinical diagnosis of Rett Syndrome in females. This test will also establish the etiology of severe neonatal encephalopathy in males.
