STRASBURG, PA & TOPEKA, IN- Researchers and clinicians through a multicenter collaboration have identified a novel multisystem disorder caused by bi-allelic variants in the CCDC47 gene. Their findings are reported in The American Journal of Human Genetics. CCDC47 is responsible for encoding an essential calcium (Ca2+)-binding protein involved in embryogenesis and development. Calcium signaling is essential for various cellular processes including muscle contraction, secretion regulation, cell proliferation, and gene transcription. In this study, detailed clinical characterization and functional studies were performed on four unrelated individuals with a complex multisystem disorder characterized by woolly hair, liver dysfunction, itchy skin, unusual facial features, low muscle tone, and global developmental delay.
