Collection Method: clinical testing

The c.216C>A (p.S72R) alteration is located in exon 5 (coding exon 4) of the POLR3E gene. This alteration results from a C to A substitution at nucleotide position 216, causing the serine (S) at amino acid position 72 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
