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.788C>A (p.A263E) alteration is located in exon 7 (coding exon 7) of the ALDH16A1 gene. This alteration results from a C to A substitution at nucleotide position 788, causing the alanine (A) at amino acid position 263 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
