Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.236G>A (p.R79Q) alteration is located in exon 3 (coding exon 2) of the POLR3GL gene. This alteration results from a G to A substitution at nucleotide position 236, causing the arginine (R) at amino acid position 79 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
