Ambry Genetics

Apr 18, 2023

The c.1049C>T (p.P350L) alteration is located in exon 8 (coding exon 8) of the MTHFSD gene. This alteration results from a C to T substitution at nucleotide position 1049, causing the proline (P) at amino acid position 350 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
