Ehlers-Danlos Syndrome Type VIIC: A Mexican Case Report
Case Reports in Dermatology
|July 13, 2012
Summary
Ehlers-Danlos syndrome (EDS) type VIIC, or human dermatosparaxis, is a rare genetic disorder causing severe skin fragility. This case study details a Mexican patient with EDS VIIC exhibiting unique skeletal abnormalities alongside typical symptoms.
Area of Science:
- Genetics
- Biochemistry
- Dermatology
Background:
- Ehlers-Danlos syndrome (EDS) encompasses a group of inherited connective tissue disorders.
- EDS type VIIC, known as human dermatosparaxis, is an autosomal recessive condition.
- It is characterized by extreme skin fragility and laxity.
Observation:
- Dermatosparaxis results from a deficiency in the enzyme responsible for processing collagen.
- This leads to impaired collagen cross-linking and structural integrity.
- The condition presents with severe skin fragility, sagging redundant skin, easy bruising, and hernias.
Findings:
- This report details a case of EDS type VIIC in a Mexican patient from consanguineous parents.
- The patient exhibited all previously described phenotypical characteristics of dermatosparaxis.
- Notably, the patient also presented with skeletal abnormalities, a feature not commonly reported.
Implications:
- This case expands the known phenotypic spectrum of EDS type VIIC.
- It highlights the importance of genetic counseling for consanguineous families with connective tissue disorders.
- Further research into the biochemical pathways and genetic variations in EDS VIIC is warranted.

01:22Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:12General Case of Eccentric Axial Loading
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical bending,...

01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:05Type IV Collagen of Basal Lamina
Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.
A type IV collagen molecule has six alpha chains which can exist in...

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
