Useful For
Providing a genetic evaluation for patients with a personal or family history suggestive of Marfan syndrome and related conditions
Establishing a diagnosis for Marfan syndrome, Loeys-Dietz syndrome, vascular Ehlers-Danlos syndrome, classic Ehlers-Danlos syndrome, and heritable thoracic aortic disease/aortopathy
Genetics Test Information
This test utilizes next-generation sequencing to detect single nucleotide and copy number variants in 30 genes associated with Marfan syndrome, Loeys-Dietz syndrome, vascular Ehlers-Danlos syndrome, hereditary aortopathies, and related phenotypes: ACTA2, ADAMTS10, ADAMTS17, BGN, CBS, COL3A1, COL5A1, COL5A2, EFEMP2, FBN1, FBN2, FLNA, LOX, LTBP3, MED12, MFAP5, MYH11, MYLK, NOTCH1, PRKG1, SKI, SLC2A10, SMAD2, SMAD3, SMAD4, SMAD6, TGFB2, TGFB3, TGFBR1, and TGFBR2. See Targeted Genes and Methodology Details for Marfan, Loeys-Dietz, and Aortopathy Gene Panel and Method Description for additional details.
Identification of a pathogenic variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for Marfan syndrome, Loeys-Dietz syndrome, vascular Ehlers-Danlos syndrome, hereditary aortopathies, and related phenotypes.
Prior Authorization is available for this assay.
