چکیده

Background and aimsPseudoxanthoma elasticum (PXE) is caused by variants in the ABCC6 gene. It results calcification skin, peripheral arteries eyes, but has considerable phenotypic variability. We investigated association between genotype clinical phenotypes these different organs.MethodsABCC6 sequencing was performed 289 PXE patients. Genotypes were grouped as two truncating, mixed, or non-truncating variants. Arterial mass quantified on whole body, low dose CT scans; arterial disease measured with ankle brachial index after treadmill test. The presence of pseudoxanthoma skin systematically scored. Ophthalmological length angioid streaks a measure Bruchs membrane calcification, choroidal neovascularizations, severity macular atrophy visual acuity. Regression models built to test age sex adjusted genotype-phenotype association.Results158 patients (median 51 years) had truncating variants, 96 54 mixed genotype, 18 47 associated lower (?: 0.39, 95%CI:-0.62;-0.17) total 0.28, 95%CI:-0.47;-0.10) scores, prevalence neovascularizations (OR: 0.41 95%CI:0.20; 0.83) compared No pseudoxanthomas found.ConclusionsPXE have less severe ophthalmological than Research into environmental genetic modifiers might provide further insights unexplained

Pseudoxanthoma elasticum

Pseudoxanthoma elasticum (PXE) is a genetic metabolic disease with autosomal recessive inheritance caused by mutations in the ABCC6 gene. The lack of functional ABCC6 protein leads to ectopic mineralization that is most apparent in the elastic tissues of the skin, eyes and blood vessels. The clinical prevalence of PXE has been estimated at between 1 per 100,000 and 1 per 25,000, with slight fem...

Placental calcification in pseudoxanthoma elasticum.

INTRODUCTION Pseudoxanthoma elasticum (PXE) is an inherited multisystem disorder of the elastic tissue and the objective of this case report is to correlate ultrasonographic and histological appearances of placental calcification in PXE. CLINICAL PICTURE We report a case of a 37-year-old white woman with PXE, whose antenatal imaging showed a markedly echogenic placenta due to extensive calcif...

MR imaging in pseudoxanthoma elasticum.

Gri:inblad-Strandberg syndrome known as pseudoxanthoma elasticum (PXE) is a rare connective tissue disorder, the inheritance of which shows both autosomal and recessive characteristics [1]. The disease most commonly involves the skin , eyes , cardiovascular system, and gastrointestinal tract [2]. The vascular connective tissue supporting the retina, known as the Bruch membrane, tends to calcify...

Periumbilical perforating pseudoxanthoma elasticum.

A 58-year-old, gravida 6, obese woman presented with a pruritic yellowish plaque around the umbilicus, which first appeared about 3 years ago. She also had flat yellow papules on the axilla and neck. After a burn from a heating device, a few perforating papules and a violaceous hue occurred on the plaque. Histological examination revealed pathological elastic fibers with a keratotic plug and pe...
