Fig. 4From: Retrospective file review shows limited genetic services fail most patients – an argument for the implementation of exome sequencing as a first-tier test in resource-constrained settingsGenetic tests of undiagnosed patients in Group C to reach a diagnosis. The most common tests ordered for Group C patients were Karyotypes and MLPA for detection of sub-telomeric deletions/duplications and known microdeletion/duplication syndromes. Single gene assays include Fragment analysis and Sanger sequencingBack to article page
