Pathogenic FBN1 variants in familial thoracic aortic aneurysms and dissections.

Clinical genetics·2015

Thoracic aortic aneurysms and dissections can be familial and distinct from Marfan syndrome. Forensic pathologists should notify families when suspecting inherited aortic disease.

Area of Science:

  • Cardiovascular Pathology
  • Genetics
  • Forensic Medicine

Background:

  • Thoracic aortic aneurysms and dissections (TAAD) are significant causes of mortality.
  • TAAD is associated with trauma, atherosclerosis, inflammation, and Marfan syndrome.
  • A familial form of TAAD, distinct from Marfan syndrome, is recognized.

Observation:

  • This report details a familial form of thoracic aortic dilatation and/or dissection.
  • The described familial condition is differentiated from Marfan syndrome.
  • The incidence of thoracic aortic aneurysms and dissections is approximately 0.6% in medicolegal autopsies.

Findings:

  • A distinct familial pattern of thoracic aortic dilatation and/or dissection exists.
  • This inherited condition is not explained by known genetic syndromes like Marfan syndrome.

  • Forensic pathology plays a role in identifying potential familial aortic diseases.

    • Implications:

    • Identifying familial TAAD is crucial for early diagnosis and intervention in at-risk relatives.
    • Forensic pathologists have a responsibility to notify families upon suspicion of heritable aortic conditions.
    • Further research into the genetic basis of non-Marfan familial TAAD is warranted.
