Genes affected

ALDH16A1 (HGNC:28114): (aldehyde dehydrogenase 16 family member A1) This gene encodes a member of the aldehyde dehydrogenase superfamily. The family members act on aldehyde substrates and use nicotinamide adenine dinucleotide phosphate (NADP) as a cofactor. This gene is conserved in chimpanzee, dog, cow, mouse, rat, and zebrafish. The protein encoded by this gene interacts with maspardin, a protein that when truncated is responsible for Mast syndrome. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2010]

The c.295G>A (p.V99I) alteration is located in exon 3 (coding exon 3) of the ALDH16A1 gene. This alteration results from a G to A substitution at nucleotide position 295, causing the valine (V) at amino acid position 99 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
