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

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...
