Genes affected

PTCH1 (HGNC:9585): (patched 1) This gene encodes a member of the patched family of proteins and a component of the hedgehog signaling pathway. Hedgehog signaling is important in embryonic development and tumorigenesis. The encoded protein is the receptor for the secreted hedgehog ligands, which include sonic hedgehog, indian hedgehog and desert hedgehog. Following binding by one of the hedgehog ligands, the encoded protein is trafficked away from the primary cilium, relieving inhibition of the G-protein-coupled receptor smoothened, which results in activation of downstream signaling. Mutations of this gene have been associated with basal cell nevus syndrome and holoprosencephaly. [provided by RefSeq, Aug 2017]

The c.-15_-4dup12 variant is located in the 5 prime untranslated region (5'UTR) of the PTCH1 gene. This variant results from a duplication of 12 nucleotides at nucleotide positions -15 to -4 upstream from the first translated codon. This nucleotide region is well conserved in available vertebrate species. Based on the available evidence, the clinical significance of this variant remains unclear. -
