Coffin-Siris syndrome (CSS) is a congenital anomaly syndrome characterized by developmental delay, coarse facial features, and hypoplasia of the fifth digit's nail or phalanges. Herein, we report a case of the 8-year-old female patient who showed developmental delay associated with dysplasia in the macular and large toe area. Comprehensive genomic analysis showed no possible candidate variants, but the subsequent genomic copy number analysis revealed a novel exonic deletion in the coding region of AT-rich interactive domain-containing protein 1B (ARID1B), a gene responsible for CSS.
