Gene Type | protein-coding |
Organism | Homo sapiens(human) |
Genome | |
Summary | This protein belongs to the aldehyde dehydrogenase family of proteins. This gene encodes a mitochondrial NAD(+)-dependent succinic semialdehyde dehydrogenase. A deficiency of this enzyme, known as 4-hydroxybutyricaciduria, is a rare inborn error in the metabolism of the neurotransmitter 4-aminobutyric acid (GABA). In response to the defect, physiologic fluids from patients accumulate GHB, a compound with numerous neuromodulatory properties. Two transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]. |

The proband was found to have compound heterozygous mutations of the succinate-semialdehyde dehydrogenase (ALDH5A1) gene, namely c.398_399delAA (p.N134X) and c.638G>T (p.R213L), for which her parents were both heterozygous carriers.

Two novel ALDH5A1 mutations likely responsible for SSADH deficiency were identified, and DNA sequencing provided an accurate diagnosis for an at-risk fetus whose sibling had SSADH deficiency. Current study and literature review identified nine additional novel mutations in eight unrelated families bringing the number of unique mutations of ALDH5A1 resulting in SSADH deficiency to 44, occurring from exon 1 to exon 10.
