Feb 28, 2023

The c.883T>C (p.C295R) alteration is located in exon 12 (coding exon 10) of the SUPT3H gene. This alteration results from a T to C substitution at nucleotide position 883, causing the cysteine (C) at amino acid position 295 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
