Official Full Name: patched 2provided by HGNC
Primary source: HGNC:HGNC:9586
See related: Ensembl:ENSG00000117425 MIM:603673; AllianceGenome:HGNC:9586
Gene type: protein coding
RefSeq status: REVIEWED

Also known as: PTC2
Summary: 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. Alterations in this gene have been associated with nevoid basal cell carcinoma syndrome, basal cell carcinoma, medulloblastoma, and susceptibility to congenital macrostomia. Alternatively spliced transcript variants have been described.[provided by RefSeq, Oct 2009]

The importance of the ATRX/DAXX pathway was confirmed by the first-ever pancreatic neuroendocrine neoplasms (pNEN)-specific protein-damaging hotspot mutation in DAXX. In this study, both novel genes, including the pro-apoptotic CYFIP2 gene and hedgehog signaling PTCH2, and novel pathways, such as the MAPK-ERK pathway, were implicated in pNEN.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
