The c.1921C>T (p.R641W) alteration is located in exon 11 (coding exon 10) of the TNS4 gene. This alteration results from a C to T substitution at nucleotide position 1921, causing the arginine (R) at amino acid position 641 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
