The c.130C>T (p.H44Y) alteration is located in exon 4 (coding exon 3) of the POLR3E gene. This alteration results from a C to T substitution at nucleotide position 130, causing the histidine (H) at amino acid position 44 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
