SLC38A11 is a putative sodium-dependent amino acid transporter belonging to the solute carrier family 38 (SLC38), also known as sodium-coupled neutral amino acid transporters (SNATs) 1. The gene encodes a membrane protein with L-amino acid transmembrane transporter activity and protein binding capacity. In Drosophila models, SLC38A11's ortholog (CG13743) is primarily expressed in the salivary gland and brain, with knockdown studies revealing critical roles in metabolic regulation; knockdown flies exhibited reduced body weight, decreased sugar consumption, altered energy storage (lipids and glycogen), and modified feeding behavior and activity patterns 1. SLC38A11 has been identified as a disease-associated gene in multiple conditions. Genome-wide association studies implicate SLC38A11 in polycystic ovary syndrome (PCOS), clustering within a metabolic changes phenotype associated with increased alkaline phosphatase levels 2. The gene shows enriched rare variant burden in type 2 diabetes susceptibility among Asian Indian families, suggesting oligogenic inheritance contributions to diabetes risk disparities in non-European populations 3. Additionally, SLC38A11 expression is upregulated in advanced prostate cancer (pT3 versus pT2 staging), though its specific prognostic value remains unclear 4. Elevated SLC38A11 mRNA levels have been observed in multiple sclerosis patients experiencing disease relapse despite immune reconstitution therapy, though this association requires further validation 5.
