Ambry Genetics

Sep 16, 2021

The c.170A>T (p.Y57F) alteration is located in exon 2 (coding exon 2) of the METTL9 gene. This alteration results from a A to T substitution at nucleotide position 170, causing the tyrosine (Y) at amino acid position 57 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
