Jul 14, 2021

The c.1258C>T (p.R420W) alteration is located in exon 10 (coding exon 9) of the TSNARE1 gene. This alteration results from a C to T substitution at nucleotide position 1258, causing the arginine (R) at amino acid position 420 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
