Template:PBB Protein patched homolog 1 is a protein that is the member of the Patched family and in humans is encoded by the PTCH1 gene.[1][2]
Function
PTCH1 is a member of the patched gene family and is the receptor for sonic hedgehog, a secreted molecule implicated in the formation of embryonic structures and in tumorigenesis. This gene functions as a tumor suppressor.
Clinical significance
Mutations of this gene have been associated with nevoid basal cell carcinoma syndrome, esophageal squamous cell carcinoma, trichoepitheliomas, transitional cell carcinomas of the bladder, as well as holoprosencephaly. Alternative splicing results in multiple transcript variants encoding different isoforms. Additional splice variants have been described, but their full length sequences and biological validity cannot be determined currently.[2]
Mutatations in PTCH1 cause Gorlin syndrome often with a midline cleft lip [3] and mutations have also been found in holoprosencephaly patients.[4][5][6] Some of these patients present cleft lip and palate among the holoprosencephaly features and missense variants in PTCH1 were also found in a sequencing screening of non syndromic cleft lip and palate patients.[7] In addition association between SNPs in or near PTCH1 have been found to be associated with non syndromic cleft lip and palate.[7][8]
