Biallelic variants in EFEMP1 in a man with a pronounced connective tissue phenotype.

ABSTRACT: Connective tissue disorders are a spectrum of diseases that affect the integrity of tissues including skin, vasculature, and joints. They are often caused by variants that disrupt genes encoding components of extracellular matrix (ECM). The fibulin glycoproteins are ECM proteins important for integrity of tissues including dermis, retina, fascia, and vasculature. The fibulin family consists of seven members (fibulins-1 to -7) and is defined by a fibulin-type domain at the C-terminus. The family is associated with human diseases, for instance a variant in FBLN1, encoding fibulin-1, is associated with synpolydactyly, while one in EFEMP1, encoding fibulin-3, causes Doyne honeycomb degeneration of the retina. Loss-of-function of fibulins-4 and -5 causes cutis laxa, while variants in fibulins-5
