Based on limited published evidence, EXOC1L (exocyst complex component 1 like) is a putative component of the exocyst complex. A genome-wide association study identified EXOC1L variants associated with blood glucose levels in East Asian populations 1. Additionally, EXOC1L variants were identified as potential genetic modifiers of age of onset in fatal familial insomnia patients, with variants absent in early-onset cases, suggesting involvement in apoptotic pathways 2. However, specific molecular functions and mechanisms remain largely unexplored.
