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.3937G>A (p.G1313R) alteration is located in exon 22 (coding exon 20) of the TNR gene. This alteration results from a G to A substitution at nucleotide position 3937, causing the glycine (G) at amino acid position 1313 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
