Ambry Genetics

Dec 01, 2022

The c.533C>T (p.T178M) alteration is located in exon 6 (coding exon 6) of the POLR1E gene. This alteration results from a C to T substitution at nucleotide position 533, causing the threonine (T) at amino acid position 178 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
