Collection Method:clinical testing

The c.500A>G (p.E167G) alteration is located in exon 7 (coding exon 6) of the POLR3GL gene. This alteration results from a A to G substitution at nucleotide position 500, causing the glutamic acid (E) at amino acid position 167 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
