Marfan syndrome, Loeys-Dietz syndrome, Familial thoracic aortic aneurysms & dissections
The Marfan Syndrome, Loeys-Dietz Syndrome, Familial Thoracic Aortic Aneurysms & Dissections, and Related Disorders NGS Panel is designed to be a cost effective method for detecting mutations in genes causing aneurysms of the aorta and its major branches. Mutations in the genes on this panel cause numerous disorders with variable but often overlapping phenotypes that should be considered in the differential diagnosis of patients presenting with aneurysms. In many instances, different mutations within any gene have been reported to result in variable phenotypes. The genes constituting this panel have been carefully selected so that they are truly representative of those associated with aneurysms of the major vessels.
The Marfan syndrome, Loeys-Dietz syndrome, Familial thoracic aortic aneurysms & dissections, and related disorders NGS panel consists of twenty-eight genes: ACTA2, BGN, CBS, COL3A1, COL5A1, COL5A2, FBN1, FBN2, FLNA, FOXE3, LOX, LTPB3, MAT2A, MFAP5, MED12, MYH11, MYLK, NOTCH1, PRKG1, SKI, SLC2A10, SMAD2, SMAD3, SMAD4, TGFB2, TGFB3, TGFBR1 and TGFBR2.
Copy number variation (CNV) analysis of the Marfan syndrome, Loeys-Dietz syndrome, Familial thoracic aortic aneurysms & dissections, and related disorders genes is also offered as a panel. Additionally, CTGT offers a comprehensive test (both NGS and CNV panels) for these genes. Panel genes are also offered as individual sequencing and deletion/duplication tests, unless otherwise indicated.
