Box 7525 Kirksville, Missouri 63501. How common is EDS? Each type of EDS has a different prevalence in the population. Bethlem myopathy 2 (BTHLM2), formerly known as myopathic-type Ehlers–Danlos syndrome, is caused by a mutation on the COL12A1 gene coding for type XII collagen. Major criteria include congenital muscle hypotonia, muscle atrophy, proximal joint contractures, and hypermobility of distal joints. ”4 Both recessive and dominant modes of inheritance have been described in patients with COL12A1‐related myopathic EDS. Likewise, Review Hypermobile Ehlers-Danlos syndrome (a. In some cases, myopathic EDS is caused by mutations in the FKBP14 gene, which provides instructions for the so-called FK506 Jun 25, 2004 · Collagen VI-related dystrophies (COL6-RDs) represent a continuum of overlapping clinical phenotypes with Bethlem muscular dystrophy at the milder end, Ullrich congenital muscular dystrophy (UCMD) at the more severe end, and a phenotype in between UCMD and Bethlem muscular dystrophy, referred to as intermediate COL6-RD. Oct 22, 2004 · Hypermobile Ehlers-Danlos syndrome (hEDS) is characterized by generalized joint hypermobility, joint instability, pain, soft and hyperextensible skin with atrophic scars and easy bruising, dental crowding, abdominal hernias, pelvic organ prolapse, marfanoid body habitus, mitral valve prolapse, and aortic root dilatation. Jan 1, 2025 · Ehlers-Danlos Syndrome Genetic Testing MOL. The Ehlers-Danlos syndromes (EDS) comprise a group of inherited connective tissue disorders presenting with variable fragility to skin, soft tissue, and certain internal organs, which can cause significant complications, particularly arterial rupture, bowel perforation and joint difficulties. a The homotrimeric domain structure of collagen XII consists of two short triple helical domains (COL1 and COL2) separated by two short noncollagenous domains (NC1 and NC2) and Clinical resource with information about Ehlers-Danlos syndrome type 7A and its clinical features, available genetic tests from US and labs around the world and links to practice guidelines and authoritative resources like GeneReviews, PubMed, MedlinePlus, clinicaltrials. aEDS is an ultra-rare disorder that affects less than 1 in 1 million people. While the genetic causes of hEDS are complex and often involve multiple genes, mutations in genes related to collagen synthesis or cross-linking, such as COL5A1 and COL5A2, have been implicated. Classical Ehlers-Danlos syndrome. These disorders, known collectively as Ehlers-Danlos syndrome , or EDS, are caused by mutations in genes that encode for collagen and collagen-related proteins. 254 Patients with Ehlers-Danlos syndrome typically present with acrogeria (distinctive facial appearance), bruising, thin skin, and vascular or visceral rupture. Subluxations, dislocations, and soft tissue injury are common; they may Jul 5, 2019 · In 2014, two groups simultaneously reported homo- or heterozygous pathogenic variants in COL12A1 in individuals suffering from a mixed myopathic and Ehlers–Danlos syndrome (EDS)–like phenotype Myopathic EDS (mEDS) Periodontal EDS (pEDS) Spondylodysplastic EDS (spEDS) Vascular EDS (vEDS) #TogetherWeDazzle. Most of the rare monogenic EDS types can have neurological features, which are often part of major or Jan 1, 2021 · Myopathic EDS’s causative gene is COL12A1 which controls the alpha chain of collagen Type 12. In addition, the skin is hyperextensible, meaning that it extends easily and snaps back after release. Myopathic EDS, which is characterized by muscle weakness and wasting, is caused by mutations in the COL12A1 gene, which encodes type XII collagen. Ehlers-Danlos syndrome is a diverse connective tissue condition that has thirteen different subtypes. Collagen XII: domains and structure, variant location, myopathic Ehlers–Danlos syndrome (EDS) criteria and clinical characteristics. Myopathic EDS (mEDS) is either autosomal dominant The small number of reported patients limits thorough investigation of this newly identified syndrome, currently coined as myopathic EDS. The inheritance of this EDS subtype can be autosomal dominant or autosomal recessive [20]. Periodontal EDS. a. Since the pragmatic proposal to consider the "hypermobile spectrum disorder" and the "hypermobile type of EDS" as one entity, disorders with the umbrella term EDS are being diagnosed more frequently. It can be either AD or autosomal recessive (AR Hypermobile EDS (hEDS) is the most common form of EDS (90% of all EDS) and the only one to not have a gene identified (yet). Another rare type of EDS is the kyphoscoliotic type of Ehlers-Danlos syndrome (EDS VIA), which is characterized by a deficiency of collagen lysyl-hydroxylase 1 due to mutations in plod1. Pathophysiology, Epidemiology, and Prognosis. People with pEDS typically have a pathogenic variant in one copy of either the C 1R or C1S gene. Targeted sequencing can be used to look at a single gene or a group of genes, known as a gene panel. Joshua A.

The geneticist said that our family medical history appears more similar to classic EDS so we need to pay more attention to vascular involvement. Oct 29, 2020 · In the very rare myopathic Ehlers-Danlos syndrome, mutations in the COL12A1 gene, which is located on chromosome 6q13-q14, lead to EDS. The specific gene affected determines the type of EDS, though the genetic causes of hypermobile Ehlers–Danlos syndrome (hEDS) are still unknown. 1720C>T, p. The genetic variants that cause EDS are many and varied in their nature. org A novel biallelic mutation in the COL12A1gene by a next-generation sequence revealed myopathic EDS.
