Ambry Genetics

Apr 17, 2024

The c.961C>T (p.P321S) alteration is located in exon 11 (coding exon 11) of the METTL17 gene. This alteration results from a C to T substitution at nucleotide position 961, causing the proline (P) at amino acid position 321 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
