Patched 2 is a protein that in humans is encoded by the PTCH2 gene.^[5]

Function[]

This gene encodes a transmembrane receptor of the patched gene family. The encoded protein may function as a tumor suppressor in the hedgehog signaling pathway.^[5]

Clinical significance[]

Alterations in this gene have been associated with nevoid basal cell carcinoma syndrome, basal cell carcinoma, medulloblastoma, and susceptibility to congenital macrostomia.^[5]
