COL27A1 (Collagen Type XXVII Alpha 1 Chain): COL27A1 is a gene that encodes a collagen protein essential for the structure and function of connective tissues. This type of collagen plays a crucial role in cartilage formation and skeletal development. Mutations in COL27A1 have been associated with disorders affecting bone and cartilage, making it a key focus in research on musculoskeletal health and potential therapeutic targets.
