Tenascin X (TN-X), also known as flexillin or hexabrachion-like protein, is a 450kDa glycoprotein, a member of the tenascin family, that is expressed in connective tissues. In humans it is encoded by the TNXB gene.^[5]

The TN-X protein is expressed in many parts of the human body, including the skin, muscles, kidneys, blood vessels, and digestive tract.^[6]^[7]

Deficiencies in the TN-X protein due to mutations or not enough of it being produced (haploinsufficiency) can lead to a rare condition called classical-like Ehlers-Danlos syndrome (EDS). People with EDS may have loose joints and weak tissues because their bodies don't make enough collagen properly.^[8]
