Elevated basal serum tryptase levels are present in 4-6% of the general population, but the cause and relevance of such increases are unknown. Previously, we described subjects with dominantly inherited elevated basal serum tryptase levels associated with multisystem complaints including cutaneous flushing and pruritus, dysautonomia, functional gastrointestinal symptoms, chronic pain, and connective tissue abnormalities, including joint hypermobility. Here we report the identification of germline duplications and triplications in the TPSAB1 gene encoding α-tryptase that segregate with inherited increases in basal serum tryptase levels in 35 families presenting with associated multisystem complaints...

Periodontal Ehlers-Danlos syndrome (pEDS) is an autosomal-dominant disorder characterized by early-onset periodontitis leading to premature loss of teeth, joint hypermobility, and mild skin findings. A locus was mapped to an approximately 5.8 Mb region at 12p13.1 but no candidate gene was identified. In an international consortium we recruited 19 independent families comprising 107 individuals with pEDS to identify the locus, characterize the clinical details in those with defined genetic causes, and try to understand the physiological basis of the condition...

INTRODUCTION: An increased risk of preterm birth in women with Joint Hypermobility Syndrome (JHS) or Ehlers-Danlos Syndrome (EDS) is suspected. MATERIAL AND METHODS: In this nationwide cohort study from 1997 through 2011, women with either JHS or EDS or both disorders were identified through the Swedish Patient Register, and linked to the Medical Birth Register. Thereby 314 singleton births to women with JHS/EDS before delivery were identified. These births were compared with 1,247,864 singleton births to women without a diagnosis of JHS/EDS...

OBJECTIVE: Ehlers-Danlos syndrome frequently causes acute and chronic pain because of joint subluxations and dislocations secondary to hypermobility. Current treatments for pain related to Ehlers-Danlos syndrome and central pain syndrome are inadequate. This case report discusses the therapeutic use of ketamine intravenous infusion as an alternative. CASE REPORT: A 27-year-old Caucasian female with a history of Ehlers-Danlos syndrome and spinal cord ischemic myelopathy resulting in central pain syndrome, presented with severe generalized body pain refractory to multiple pharmacological interventions...

Ehlers-Danlos syndrome (EDS) encompasses a genetically and clinically heterogeneous group of connective tissue disorders, characterized by joint hypermobility, skin hyperextensibility and tissue fragility. It is a rare condition, and inheritance is either autosomal dominant or recessive. Previously grouped into 11 different subtypes, with increasing knowledge of the underlying molecular defects, it was reclassified in 1997 into 6 major groups, with type VIII excluded from this classification. Type VIII EDS is a very rare subtype, characterized by severe, early-onset periodontitis, skin fragility and abnormal scarring...

PURPOSE: Thoracic aortic aneurysm and dissection (TAAD) is typically inherited in an autosomal dominant manner, but rare X-linked families have been described. So far, the only known X-linked gene is FLNA, which is associated with the periventricular nodular heterotopia type of Ehlers-Danlos syndrome. However, mutations in this gene explain only a small number of X-linked TAAD families. METHODS: We performed targeted resequencing of 368 candidate genes in a cohort of 11 molecularly unexplained Marfan probands...

The tenascin-X (TNX) deficient type Ehlers-Danlos syndrome (EDS) is similar to the classical type of Ehlers-Danlos syndrome. Due to the limited awareness among geneticists and the challenge of the molecular analysis of the TNXB gene, the TNX-deficient type EDS is likely to be under diagnosed. We therefore performed an observational, cross-sectional study. History and physical examination were performed. Results of serum TNX measurements were collected and mutation analysis was performed by a combination of NGS, Sanger sequencing and MLPA...

INTRODUCTION: The Ehlers-Danlos syndrome, hypermobility type (EDS-HT) is a rare genetic disease. Diagnosis is based on a combination of clinical criteria described in the classification of Villefranche. Diagnosis is difficult to make because of the lack of specific clinical signs and the absence of genetic testing. The EDS-TH manifests itself manly by musculoskeletal pain and joint hypermobility. Temporomandibular disorders (TMD) are also reported. Our aim was to objectify the presence and to qualify the type of TMD associated with the EDS-HT in order to propose an additional diagnostic argument...

Joint hypermobility syndrome/Ehlers-Danlos syndrome hypermobility type (JHS/EDS-HT), is likely the most common systemic heritable connective tissue disorder, and is mostly recognized by generalized joint hypermobility, joint instability complications, minor skin changes and a wide range of satellite features. JHS/EDS-HT is considered an autosomal dominant trait but is still without a defined molecular basis. The absence of (a) causative gene(s) for JHS/EDS-HT is likely attributable to marked genetic heterogeneity and/or interaction of multiple loci...

Syndromic thoracic aortic aneurysm and dissection (TAAD) can suggest Marfan, vascular Ehlers-Danlos or Loeys-Dietz (LDS) syndromes. Several of the TGFβ-pathway related genes predispose to different types of LDS. Heterozygous loss-of-function variations in TGFβ2 have been shown to be responsible for a novel form of syndromic TAAD associated with an impairment of the mitral valve and cerebrovascular disease called Loeys-Dietz syndrome type 4 (LDS4). We report the clinical characterization of a LDS4 French family with sudden deaths and diffuse vascular lesions, caused by a frameshift mutation in TGFβ2 gene: c...

Ehlers-Danlos syndrome (EDS) is a group of heritable disorders characterised by vast clinical heterogeneity ranging from the classic constellation of symptoms including skin hyperextensibility, joint hypermobility and skin fragility to the exceedingly critical consequences of arterial rupture and visceral perforation. We describe the case of a 65-year-old male with a history of classic EDS who reported of dyspnoea on exertion, orthopnoea, fatigue and palpitations. He was found to have dilated cardiomyopathy with an ejection fraction of 35%, aortic root dilation and severe aortic valve regurgitation...

PURPOSE: The patients diagnosed with Ehlers-Danlos Syndrome Hypermobility Type (EDS-HT) are characterized by pain, proprioceptive inacuity, muscle weakness, potentially leading to activity limitations. In EDS-HT, a direct relationship between muscle strength, proprioception and activity limitations has never been studied. The objective of the study was to establish the association between muscle strength and activity limitations and the impact of proprioception on this association in EDS-HT patients...

BACKGROUND: Patients with celiac disease (CD) often have articular complaints, and small prior studies suggest an association with Ehlers-Danlos syndrome (EDS)/joint hypermobility syndrome (JHS). AIMS: This study examines the risks of EDS/JHS in patients with CD. METHODS: This cohort study compared all individuals in Sweden diagnosed with CD based on small intestinal biopsy between 1969-2008 (n=28,631) to 139,832 matched reference individuals, and to a second reference group undergoing biopsy without having CD (n=16,104)...
