Mutations in the following genes are considered causative of Stickler syndrome: COL2A1 (OMIM, no. 120140) [4], COL11A1 (OMIM, no. 120280) [5], COL11A2 (OMIM, no. 120290) [6], COL9A1 (OMIM, no. 120210) [7], COL9A2 (OMIM, no. 120260) [8], COL9A3 (OMIM, no. 120270) [9], and LOXL3 (OMIM, no. 607163) [10]. This evidence concerns the gene COL9A3 and Stickler syndrome.
