Pseudoxanthoma elasticum (PXE), caused by ABCC6/MRP6 mutation, is a heritable multisystem disorder in humans. The progressive clinical manifestations of PXE are accompanied by ectopic mineralization in various connective tissues. However, the pathomechanisms underlying the PXE multisystem disorder remains obscure, and effective treatment is currently available. In this study, we generated zebrafish abcc6a mutants using the transcription activator-like effector nuclease (TALEN) technique. In young adult zebrafish, abcc6a is expressed in the eyes, heart, intestine, and other tissues. abcc6a mutants exhibit extensive calcification in the ocular sclera and Bruch’s membrane, recapitulating part of the PXE manifestations. Mutations in abcc6a upregulate extracellular matrix (ECM) genes, leading to fibrotic heart with reduced cardiomyocyte number. We found that abcc6a mutation reduced levels of both vitamin K and pyrophosphate (PPi) in the serum and diverse tissues. Vitamin K administration increased the gamma-glutamyl carboxylated form of matrix gla protein (cMGP), alleviating ectopic calcification and fibrosis in vertebrae, eyes, and hearts. Our findings contribute to a comprehensive understanding of PXE pathophysiology from zebrafish models.

Background: Pseudoxanthoma elasticum (PXE) is a rare hereditary disease caused by mutations in the ABCC6 gene, characterized by ectopic calcification of connective tissue throughout the body. Vascular conditions associated with PXE have been well-documented in the literature, but to our knowledge, analysis of the myriad of PXE case reports with associated vascular diseases in addition to larger cohort studies, has not been undertaken. Objective: To review existing literature reporting peripheral vascular disease (PVD), cardiovascular disease (CVD), cerebrovascular disease (CeVD), hypertension, and carotid rete mirabile (CRM) in PXE patients as of June 2021. Methods: A search of the PubMed database using the key words “pseudoxanthoma elasticum” and “vascular” was performed. Results: A total of 345 cases of PVD, 97 cases of CVD, and 123 case of CeVD were reported.  Additionally, 88 cases of hypertension and 5 cases of CRM were reported. Conclusions: PXE patients are at risk of developing serious vascular conditions, particularly peripheral vascular disease.  This condition also appears to have some connection to carotid rete mirabile, which is extremely rare in humans.  Further research should be conducted to analyze the connection between PXE and CRM in order to better understand and treat both conditions.
