Specifically, we selected synaptojanin 1⁄2 (SYNJ1/2), INPP5E, INPP5J, oculocerebrorenal syndrome of Lowe (OCRL), INPP5B, and INPP5K, of which INPP5E/B and OCRL have already been shown to alter ciliary lipid composition [54, 56]. This evidence concerns the gene INPP5K and oculocerebrorenal syndrome.
