Mar 24, 2023

The c.190C>T (p.R64W) alteration is located in exon 2 (coding exon 1) of the TPRG1 gene. This alteration results from a C to T substitution at nucleotide position 190, causing the arginine (R) at amino acid position 64 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
