title: Selected disorders of connective tissue: pseudoxanthoma elasticum, cutis laxa, and lipoid proteinosis.
abstract: There has been progress made in the understanding of 3 Mendelian disorders: pseudoxanthoma elasticum, cutis laxa, and lipoid proteinosis cutis and mucosae. While they are primary connective tissue diseases, their names imply a connection to the skin, and in fact, it is often the dermatologist who makes the diagnosis. It seems rational that defects in various extracellular matrix proteins cause lipoid proteinosis or subtypes of cutis laxa, yet the discovery of a liver- and kidney-based transmembrane transporter as the culprit of pseudoxanthoma elasticum was rather surprising and may shed new light on elastic tissue homeostasis.
