Ambry Genetics

May 10, 2024

The c.1811C>T (p.P604L) alteration is located in exon 15 (coding exon 15) of the YTHDC1 gene. This alteration results from a C to T substitution at nucleotide position 1811, causing the proline (P) at amino acid position 604 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
