Genes affected

ALDH1L1 (HGNC:3978): (aldehyde dehydrogenase 1 family member L1) The protein encoded by this gene catalyzes the conversion of 10-formyltetrahydrofolate, nicotinamide adenine dinucleotide phosphate (NADP+), and water to tetrahydrofolate, NADPH, and carbon dioxide. The encoded protein belongs to the aldehyde dehydrogenase family. Loss of function or expression of this gene is associated with decreased apoptosis, increased cell motility, and cancer progression. There is an antisense transcript that overlaps on the opposite strand with this gene locus. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2012]

The c.2105A>T (p.N702I) alteration is located in exon 19 (coding exon 18) of the ALDH1L1 gene. This alteration results from a A to T substitution at nucleotide position 2105, causing the asparagine (N) at amino acid position 702 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
