Ambry Genetics

Jul 20, 2022

The c.166G>A (p.A56T) alteration is located in exon 3 (coding exon 1) of the RNMT gene. This alteration results from a G to A substitution at nucleotide position 166, causing the alanine (A) at amino acid position 56 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
