Genes affected

MTHFD1L (HGNC:21055): (methylenetetrahydrofolate dehydrogenase (NADP+ dependent) 1 like) The protein encoded by this gene is involved in the synthesis of tetrahydrofolate (THF) in the mitochondrion. THF is important in the de novo synthesis of purines and thymidylate and in the regeneration of methionine from homocysteine. Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jun 2011]

The c.128G>C (p.R43P) alteration is located in exon 1 (coding exon 1) of the MTHFD1L gene. This alteration results from a G to C substitution at nucleotide position 128, causing the arginine (R) at amino acid position 43 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
