Based on limited published evidence, LRRC30 is a leucine-rich repeat containing protein annotated for involvement in intracellular signal transduction. LRRC30 is preferentially expressed in skeletal muscle tissue with potential tissue-specific epigenetic regulation 1. The gene has been identified as a candidate prognostic biomarker in ovarian serous cystadenocarcinoma, suggesting dysregulation in cancer pathways 2. However, detailed molecular functions and mechanisms remain largely undescribed in the literature.
