Loeys-Dietz Syndrome

A 37-year-old woman with LDS presented with numerous facial milia. She reported that the milia had been present since early childhood. Inspection of her skin revealed numerous striae. [jamanetwork.com]

We have given presentations at Grand Rounds in various hospitals. We have created a medical presentation and the “Head-to-Toe” checklist that we have presented to over 1300 medical professionals from around the world. [loeysdietzcanada.org]

TAAs were present in 67% of the cases (4/6), and in Leutermann et al. aneurysms were present in two of the family members [ 18 ],[ 19 ]. [bmcmedgenet.biomedcentral.com]

Although there is at present no standardized diagnostic method for DE in LDS, some qualitative [6], [8] and quantitative methods [9], [12], [13] have been used. [journals.plos.org]

  • Cutaneous Manifestation

    We present these findings to further characterize the cutaneous manifestations of LDS, to expand the differential for facial milia, and, most importantly, to increase awareness of possible presenting features of LDS, a recently described and potentially [jamanetwork.com]

    Craniofacial signs as ocular hypertelorism, bifid uvula/cleft palate or craniosynostosis and cutaneous manifestations, as velvety and translucent skin, easy bruising, atrophic scars, are also present at variable degree [ 2 ],[ 3 ],[ 9 ],[ 11 ]. [bmcmedgenet.biomedcentral.com]

  • Thin Skin

    Features shared with LDS, but not MFS, include hypertelorism, bifid uvula, bicuspid aortic valve, mitral valve prolapse (MVP), arterial tortuosity, club feet, and thin skin with easy bruising [ 16 ]. [bmcmedgenet.biomedcentral.com]

  • Striae Distensae

    Features shared with MFS and LDS include aortic aneurysm, mainly in thoracic tract, pectus deformity, arachnodactyly, scoliosis, joint hypermobility, and striae distensae in young age. [bmcmedgenet.biomedcentral.com]

  • Strabismus

    People with Loeys-Dietz syndrome have unique facial features, like widely spaced eyes, an opening in the roof in the mouth ( cleft palate ), and eyes that don’t point in the same direction ( strabismus ) — but no two people with the disorder are alike [healthline.com]

  • Hypertelorism

    The classical triad of Loeys-Dietz syndrome is described as 1 : arterial tortuosity and aneurysms hypertelorism bifid uvula or cleft palate Loeys-Dietz syndrome is rare, with prevalence estimated at less than one per 100,000. [radiopaedia.org]

    Other facial features included hypertelorism and retrognathia. The oral cavity was notable for a high-arched palate and a broad uvula. [jamanetwork.com]

    It is characterised by aortic and peripheral aneurysms and arterial tortuosity, bifid uvula and/or cleft palate, and hypertelorism, and is caused by mutations in the genes for the transforming growth factor β receptors 1 or 2 ( TGFBR1 at chromosome 9q33 [ncbi.nlm.nih.gov]

    Other features of Loeys-Dietz syndrome include: Cardiovascular Arteries that twist and wind (arterial tortuosity) Heart defects at birth (atrial septal defect, patent ductus arteriosis, bicuspid aortic valve) Eyes, Head and Neck Widely-spaced eyes (hypertelorism [marfan.org]

    Most individuals with this disorder have craniofacial features that include hypertelorism (widely spaced eyes) and a bifid or broad uvula. [hopkinsmedicine.org]

Thus, it will be some time before they are used for routine clinical assessment of the vascular system in general and the workup of patients with LDS. Conclusion LDS is a recently described inherited vasculopathic syndrome. [pubs.rsna.org]

Studies are ongoing to determine whether drug treatment of the Loeys-Dietz syndrome also may be of value. [medicinenet.com]

It’s important to meet with a doctor who is familiar with the disorder in order to determine a treatment plan. There’s no cure for the disorder, so treatment is aimed at preventing and treating symptoms. [healthline.com]

Current surgical experience with LDS is excellent, offering a good long-term prognosis with timely identification of the disease. [insights.ovid.com]

In contrast to Loeys-Dietz syndrome, in other inherited syndromes associated with aortic aneurysms, surgery carries a poorer prognosis, and the aneurysms can be managed with medications for a longer period of time before surgery becomes necessary. [medicinenet.com]

There’s no cure for the disorder, so treatment is aimed at preventing and treating symptoms. Due to the high risk of rupture, someone with this condition should be followed closely to monitor the formation of aneurysms and other complications. [healthline.com]
