Overview
Ehlers-Danlos syndrome, fibronectinemic type (also sometimes called EDS with fibronectin deficiency or fibronectinemic EDS) is a rare and now considered obsolete subtype of Ehlers-Danlos syndrome (EDS) — a group of inherited connective tissue disorders. The term 'obsolete' means that modern medical classification systems no longer recognize this as a separate, well-defined subtype, largely because the scientific evidence supporting fibronectin as the primary cause was not confirmed in later research. Historically, this condition was described in a small number of patients who had features typical of EDS along with abnormalities in fibronectin, a protein that helps hold the body's connective tissues together. Connective tissue acts like the body's glue, supporting skin, joints, blood vessels, and internal organs. When it does not work properly, people can experience very stretchy or fragile skin, joints that move too far (hypermobility), chronic pain, and easy bruising. Because this subtype is no longer officially classified, patients who were previously given this diagnosis may now be reclassified under one of the currently recognized EDS subtypes or another connective tissue disorder. If you or a family member carries this diagnosis, speaking with a clinical geneticist is strongly recommended to get an updated evaluation using current diagnostic criteria.
