Ambry Genetics

Feb 12, 2024

The c.550C>T (p.H184Y) alteration is located in exon 4 (coding exon 4) of the MTHFD2L gene. This alteration results from a C to T substitution at nucleotide position 550, causing the histidine (H) at amino acid position 184 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
