**Background of ALDH3A2**
ALDH3A2 (aldehyde dehydrogenase 3 family member A2), also known as fatty aldehyde dehydrogenase (FALDH), is a critical enzyme in the aldehyde dehydrogenase (ALDH) superfamily. This enzyme plays a pivotal role in lipid metabolism, specifically in the oxidation of fatty aldehydes to their corresponding carboxylic acids. It is localized in the endoplasmic reticulum and primarily expressed in skin, liver, and kidney tissues. ALDH3A2 catalyzes the NAD+-dependent conversion of long-chain aliphatic aldehydes, generated during sphingosine breakdown or ether glycerolipid metabolism, into non-toxic fatty acids, which are further utilized in cellular processes or energy production.
Mutations in the *ALDH3A2* gene are linked to Sjögren-Larsson syndrome (SLS), a rare autosomal recessive disorder characterized by ichthyosis, intellectual disability, and spastic diplegia. These mutations impair enzyme activity, leading to toxic fatty aldehyde accumulation in tissues, which disrupts membrane integrity and signaling pathways. The gene, located on chromosome 17p11.2. spans ~31 kb and contains 11 exons.
Research on ALDH3A2 focuses on understanding its role in lipid homeostasis, cellular detoxification, and its association with metabolic disorders. Therapeutic strategies, such as gene therapy or enzyme replacement, are under exploration for SLS. Its broader relevance in oxidative stress and lipid-related diseases underscores its importance in biomedical studies.
