Ambry Genetics

Feb 28, 2023

The c.655G>T (p.A219S) alteration is located in exon 2 (coding exon 2) of the METTL13 gene. This alteration results from a G to T substitution at nucleotide position 655, causing the alanine (A) at amino acid position 219 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
