Dec 22, 2023

The c.796C>T (p.R266W) alteration is located in exon 6 (coding exon 4) of the TEKT3 gene. This alteration results from a C to T substitution at nucleotide position 796, causing the arginine (R) at amino acid position 266 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
