Genes affected

ALDH1L2 (HGNC:26777): (aldehyde dehydrogenase 1 family member L2) This gene encodes a member of both the aldehyde dehydrogenase superfamily and the formyl transferase superfamily. This member is the mitochondrial form of 10-formyltetrahydrofolate dehydrogenase (FDH), which converts 10-formyltetrahydrofolate to tetrahydrofolate and CO2 in an NADP(+)-dependent reaction, and plays an essential role in the distribution of one-carbon groups between the cytosolic and mitochondrial compartments of the cell. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Oct 2010]

The c.1540G>T (p.A514S) alteration is located in exon 13 (coding exon 13) of the ALDH1L2 gene. This alteration results from a G to T substitution at nucleotide position 1540, causing the alanine (A) at amino acid position 514 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
