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]

The c.3358A>G (p.I1120V) alteration is located in exon 18 (coding exon 16) of the TNR gene. This alteration results from a A to G substitution at nucleotide position 3358, causing the isoleucine (I) at amino acid position 1120 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
