In addition to sequencing using genomic sequencing (“next generation sequencing” or "NGS"), a range of other testing methodologies may be needed to identify pathogenic changes in the genes in the panel including:
- Sanger sequencing
- long range PCR
- copy number analysis (e.g. MLPA)
- fragment analysis
Information about DNA tests and testing laboratories is available from:
If these genes are tested using genomic sequencing (“next generation sequencing” or NGS), and testing has not identified a pathogenic variant, the value of testing using another methodology (e.g. MLPA, Sanger sequencing) should be considered.
If genetic testing in DNA from peripheral blood is uninformative, testing of two or more different tumour samples may be indicated to assess for mosaicism.
