The c.892C>G (p.L298V) alteration is located in exon 10 (coding exon 10) of the POLR1E gene. This alteration results from a C to G substitution at nucleotide position 892, causing the leucine (L) at amino acid position 298 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
