FKBP14 mutation analysis should be considered in all individuals with apparent kyphoscoliotic type of EDS and normal urinary pyridinoline excretion, in particular in conjunction with sensorineural hearing impairment.
Col5a2, a gene previously not specifically linked to MI response but responsible for the classic type of Ehlers-Danlos syndrome, was found to have many and strong co-expression associations within this community (11 connections with ρ > 0.85).
IL1R2 hypomethylation and AR hypermethylation may constitute an important determinant of disease severity, whereas NPR2 hypomethylation and SP140 hypermethylation may provide a biomarker for vulnerability to EDS in OSA.
Natriuretic peptide receptor 2 (NPR2) promoter methylation (-608/-618 CpG sites) were decreased, whereas levels of both NPR2 and serum C type natriuretic peptide protein were increased in the SDB patients with EDS.
Tenascin X (TNX) deficiency is a rare type of EDS, defined as classical-like EDS (clEDS), since it phenotypically resembles the classical form of EDS, though lacking atrophic scarring.
A heterozygous deletion of exon 9 in the COL1A2-mRNA of a patient with symptoms of both the Ehlers-Danlos-Syndrome and the Osteogensis Imperfecta is described.
A large kindred with EDS type IV was studied clinically, and the biochemical defects and underlying mutation in the COL3A1 gene that encodes the chains of type III procollagen were identified.
A sequencing analysis of the COL3A1 gene identified a novel, de novo missense mutation that confirmed the diagnosis of vascular Ehlers-Danlos syndrome (EDS).
A single-base mutation in intron 37 of the gene for type III procollagen (COL3A1) was found in a proband with the type IV variant of Ehlers-Danlos syndrome.
Accordingly, our major findings (vascular smooth muscle cells with small nuclei, small percentage of elastic membrane area per tunica media, many large elastic flaps) should be considered vulnerable characteristics indicating fragility of the aorta in patients with spEDS-ZIP13.
All patients show signs of Ehlers-Danlos syndrome (EDS): soft skin with abundant subcutaneous tissue and joint laxity, hernias, and disorganization of the extracellular matrix (ECM) of fibronectin (FN) and of actin microfilaments in cultured skin fibroblasts.

Although the precise role of TNX in the pathogenesis of EDS is uncertain, this patient's findings suggest a unique and essential role for TNX in connective-tissue structure and function.
Although vascular Ehlers-Danlos syndrome appears to be genetically homogeneous, allelic heterogeneity is marked, and the natural history varies with gender and type of mutation in COL3A1.
Among 28 markers analyzed, homozygosity was only observed for D5S469 and D5S2111, which were markers for galactosyltransferase-I (B4GALT7) located on chromosome 5q35.2, where the previously reported progeroid-like variant of EDS has been mapped.
