Introduction Congenital anomalies (CAs) constitute a significant determinant of neonatal mortality in India, and past studies have elucidated their diverse clinical presentations across different geographic regions. Given the limited availability of region-specific data in our locale, this study was initiated to elucidate the prevalence and phenotypic manifestations of congenital anomalies in live births within the distinctive setting of the Andaman and Nicobar Islands, India. Methods This retrospective observational study was conducted at the Department of Pediatrics of the Andaman and Nicobar Islands Institute of Medical Sciences (ANIIMS), located in Port Blair, during a defined one-year period extending from June 2022 to May 2023.
