GOLGA8A is a golgin family protein localized to the cis-Golgi network and Golgi cisterna membranes, with a putative role in maintaining Golgi structure 1. However, its precise molecular function remains poorly characterized. GOLGA8A has emerged as a significant disease-associated gene: a tandem repeat expansion in GOLGA8A intron is present in nearly 60% of atypical frontotemporal lobar degeneration with ubiquitin-positive inclusions (aFTLD-U) cases and represents a major genetic risk factor (odds ratio 26.7) for this young-onset dementia 1. Beyond neurodegeneration, GOLGA8A expression is dysregulated across multiple pathological conditions—elevated in blood samples from intracerebral hemorrhage patients 2 and altered in psychiatric disorders including obsessive-compulsive disorder, where it comprises part of a diagnostic gene signature 3. GOLGA8A is also implicated in cancer progression, appearing in prognostic signatures for colorectal cancer 4, bladder cancer 5, gastric cancer 6, and lung adenocarcinoma with lymph node metastasis 7. Additionally, GOLGA8A is a downstream target of the long noncoding RNA GAS6-AS1 in atrial fibrillation-related stroke pathogenesis 8. Despite its consistent association with diverse diseases, the functional consequences of GOLGA8A dysregulation remain unknown, requiring mechanistic investigation to clarify its roles in cellular homeostasis and disease pathogenesis.
