The exome test includes all coding genes in the human genome. Although we perform exome sequencing on those patients, we demonstrate that a first tier analysis should include targeted interpretation of ~100 genes strongly associated with the disease. This analysis provides diagnoses in ~11% of the patients. Follow up parental testing on a limited number of patients (n=15) that had inconclusive results, revealed de novo (new mutations) variant status, leading to upgrade to positive reports in 7 patients and adding ~5% to the overall diagnostic yield.
