The next generation sequencing panel detects 70-99% of the reported mutations in these genes using this testing methodology. Many genes on this panel result in rare or overlapping phenotypes, and the clinical sensitivity of gene sequencing has not been determined. The clinical sensitivity of single gene testing is dependent on …

Large exonic deletions, duplications, or insertions have been reported in several of these genes. Deletion/duplication analysis may be indicated as a follow-up test in patients with a single mutation in one of these genes, or in patients with normal Liver Panel analysis.
