The c.517G>C (p.V173L) alteration is located in exon 8 (coding exon 6) of the SUPT3H gene. This alteration results from a G to C substitution at nucleotide position 517, causing the valine (V) at amino acid position 173 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
