Genes affected

TNR (HGNC:11953): (tenascin R) This gene encodes a member of the tenascin family of extracellular matrix glycoproteins. The encoded protein is restricted to the central nervous system. The protein may play a role in neurite outgrowth, neural cell adhesion and modulation of sodium channel function. It is a constituent of perineuronal nets. [provided by RefSeq, Aug 2013]

TNR Gene-Disease associations (from GenCC):

• neurodevelopmental disorder, nonprogressive, with spasticity and transient opisthotonus
