Genes affected
ALDH9A1 (HGNC:412): (aldehyde dehydrogenase 9 family member A1) This protein belongs to the aldehyde dehydrogenase family of proteins. It has a high activity for oxidation of gamma-aminobutyraldehyde and other amino aldehydes. The enzyme catalyzes the dehydrogenation of gamma-aminobutyraldehyde to gamma-aminobutyric acid (GABA). This isozyme is a tetramer of identical 54-kD subunits. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2024The c.910A>G (p.N304D) alteration is located in exon 6 (coding exon 6) of the ALDH9A1 gene. This alteration results from a A to G substitution at nucleotide position 910, causing the asparagine (N) at amino acid position 304 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
