Ambry Genetics

Jun 29, 2023

The c.121G>C (p.A41P) alteration is located in exon 2 (coding exon 1) of the METTL6 gene. This alteration results from a G to C substitution at nucleotide position 121, causing the alanine (A) at amino acid position 41 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
