  • Dermatomyositis associated with Generalized subcutaneous Edema and Evans syndrome.
    Journal of the American Academy of Dermatology, 2012
    Co-Authors: Kyu Dong Jung, Pyoung Su Kim, Hae Young Park, Cho Rok Kim, Ji-yeon Byun, Joo Heung Lee, Jun-mo Yang, Eil-soo Lee
    Abstract:

    Although periorbital Edema is a common manifestation of dermatomyositis (DM), Generalized subcutaneous Edema associated with DM is extremely rare. Evans syndrome is an autoimmune disease in which an individual's antibodies attack one's own red blood cells and platelets. Evans syndrome is rarely a presenting feature of DM. DM has been rarely reported to be associated with either Generalized Edema or Evans syndrome. We report the case of a 52-year-old Korean woman who presented with Generalized subcutaneous Edema, an erythematous rash, dysphagia, and proximal muscle weakness, and subsequently developed features of Evans syndrome. Treatment with high-dose glucocorticoids and an immunosuppressive agent controlled the DM, the Generalized subcutaneous Edema, and the Evans syndrome.

  • a novel ccbe1 mutation leading to a mild form of hennekam syndrome case report and review of the literature
    BMC Medical Genetics, 2015
    Co-Authors: Patrick Frosk, Bernard N Chodirker, Louise R Simard, Wael Elmatary, Ana Hanlondearman, Jeremy Schwartzentruber, Jacek Majewski, Cheryl Rockmangreenberg
    Abstract:

    Background: Mutations in CCBE1 have been found to be responsible for a subset of families with autosomal recessive Hennekam syndrome. Hennekam syndrome is defined as the combination of Generalized lymphatic dysplasia (ie. lymphEdema and lymphangiectasia), variable intellectual disability and characteristic dysmorphic features. The patient we describe here has a lymphatic dysplasia without intellectual disability or dysmorphism caused by mutation in CCBE1, highlighting the phenotypic variability that can be seen with abnormalities in this gene. Case presentation: Our patient is a 5 week old child of Pakistani descent who presented to our center with Generalized Edema, ascites, and hypoalbuminemia. She was diagnosed with a protein losing enteropathy secondary to segmental primary intestinal lymphangiectasia. As the Generalized Edema resolved, it became clear that she had mild persistent lymphEdema in her hands and feet. No other abnormalities were noted on examination and development was unremarkable at 27 months of age. Given the suspected genetic etiology and the consanguinity in the family, we used a combination of SNP genotyping and exome sequencing to identify the underlying cause of her disease. We identified several large stretches of homozygosity in the patient that allowed us to sort the variants found in the patient’s exome to identify p.C98W in CCBE1 as the likely pathogenic variant. Conclusions: CCBE1 mutation analysis should be considered in all patients with unexplained lymphatic dysplasia even without the other features of classic Hennekam syndrome.

  • ephb4 kinase inactivating mutations cause autosomal dominant lymphatic related hydrops fetalis
    Journal of Clinical Investigation, 2016

    Abstract:

    Hydrops fetalis describes fluid accumulation in at least 2 fetal compartments, including abdominal cavities, pleura, and pericardium, or in body tissue. The majority of hydrops fetalis cases are nonimmune conditions that present with Generalized Edema of the fetus, and approximately 15% of these nonimmune cases result from a lymphatic abnormality. Here, we have identified an autosomal dominant, inherited form of lymphatic-related (nonimmune) hydrops fetalis (LRHF). Independent exome sequencing projects on 2 families with a history of in utero and neonatal deaths associated with nonimmune hydrops fetalis uncovered 2 heterozygous missense variants in the gene encoding Eph receptor B4 (EPHB4). Biochemical analysis determined that the mutant EPHB4 proteins are devoid of tyrosine kinase activity, indicating that loss of EPHB4 signaling contributes to LRHF pathogenesis. Further, inactivation of Ephb4 in lymphatic endothelial cells of developing mouse embryos led to defective lymphovenous valve formation and consequent subcutaneous Edema. Together, these findings identify EPHB4 as a critical regulator of early lymphatic vascular development and demonstrate that mutations in the gene can cause an autosomal dominant form of LRHF that is associated with a high mortality rate.
