NCT04005976

Brief Summary

The Montalcino Aortic Consortium (MAC) will provide the infrastructure to assemble large cohorts of patients with mutations in known heritable thoracic aortic disease (H-TAD) genes, define the phenotype associated with these genes, and determine genetic and environmental modifiers of H-TAD.

Eligibility Criteria

Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Individuals with a known mutation for H-TAD and their relatives who also carry the mutation

You may qualify if:

  • Patients and their relatives with a confirmed pathogenic, likely pathogenic variant, or variant of unknown clinical significance in at least one of the H-TAD genes (i.e. TGFBR1, TGFBR2, SMAD3, TGFB2, TGFB3, ACTA2, MYH11, MYLK, PRKG1, MAT2A, MFAP5, LOX, COL3A1, FOXE3, and FBN1).
  • Patients of all ages, sex and race for which informed consent can be obtained.

You may not qualify if:

  • Patients without a confirmed causative variant for H-TAD.
