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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 22, 2024The c.1030C>G (p.H344D) alteration is located in exon 10 (coding exon 10) of the MTHFD1L gene. This alteration results from a C to G substitution at nucleotide position 1030, causing the histidine (H) at amino acid position 344 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
