Because TTLL11 is a ciliary protein and because the TTLL5 (also from the TTLLs family) and the ciliary protein POC5 was found to be implicated in scoliosis and retinal function1,42,62, histology of mut-ttll11 retinal tissue was assessed and revealed a disorganisation of the double cone cell layer. This evidence concerns the gene TTLL5 and scoliosis.
