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 GeneticsOct 07, 2022The c.548C>T (p.P183L) alteration is located in exon 4 (coding exon 4) of the ALDH9A1 gene. This alteration results from a C to T substitution at nucleotide position 548, causing the proline (P) at amino acid position 183 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
