For this panel we offer DNA sequence analysis of the SDHB, SDHC, SDHD, SDHAF2, MAX, and TMEM127 genes. PCR amplification and sequencing is performed on all coding exons including splice junctions. The patient’s gene sequence is then compared to a reference sequence. Sequence variants are classified as mutations, variants of unknown significance or benign variants unrelated to disease. Variants of unknown significance may warrant further studies in the patient and other family members. Mutations in promoters, deep intronic regions and other regulatory regions will not be identified with this assay. Deletion/duplication testing is also perfomed in this panel for the genes SDHB, SDHC, SDHD, and SDHAF2. Large deletions and duplications will be detected using multiplex ligation-dependent probe amplification assay (MLPA).
Test results with interpretation will be mailed and/or faxed to the referring physician or send out lab following completion of the test. Additional reports will be provided as requested.
Molecular diagnosis of affected individuals allows pre-symptomatic screening of at risk family members and leads to early detection and timely intervention in the disease process.
