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.3370G>A (p.A1124T) alteration is located in exon 18 (coding exon 16) of the TNR gene. This alteration results from a G to A substitution at nucleotide position 3370, causing the alanine (A) at amino acid position 1124 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
