PIK3C2A-Related Clinical Phenotype and Cellular Charaterization Linked to Functional SHH Primary Cilia Defect.

ABSTRACT: PIK3C2A is a member of the class II phosphatidylinositol-3-kinases (PI3K) family that catalyzes the phosphorylation of phosphatidylinositol (PI) into PI(3)P and of PI(4)P into PI(3,4)P2. These second messenger lipids regulate a wide range of downstream signaling pathways involved in many physiological functions and cellular processes, including cell proliferation, growth, survival, motility, and metabolism. PIK3C2A is also involved in the regulation of primary cilia formation and maintenance and in the regulation of receptor-mediated endocytosis at the base of the cilium. PIK3C2A was recently related to a novel oculoskeletodental syndrome (OCSKD MIM#618440), combining short stature, coarse facial features, ocular, and skeletal abnormalities. We describe here the fifth family presenting a P
