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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.3913C>T (p.R1305W) alteration is located in exon 22 (coding exon 20) of the TNR gene. This alteration results from a C to T substitution at nucleotide position 3913, causing the arginine (R) at amino acid position 1305 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
