Genes affected

PTCH2 (HGNC:9586): (patched 2) 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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1598T>C (p.I533T) alteration is located in exon 13 (coding exon 13) of the PTCH2 gene. This alteration results from a T to C substitution at nucleotide position 1598, causing the isoleucine (I) at amino acid position 533 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
