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