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.1067+5 G>C variant has not been published as a pathogenic variant, nor has it been reported asa benign variant to our knowledge. It was not observed with any significant frequency inapproximately 6,500 individuals of European and African American ancestry in the NHLBI ExomeSequencing Project. Several in-silico splice prediction models predict that c.1067+5 G>C may damagethe natural splice donor site for IVS7 and lead to abnormal gene splicing. However, in the absence ofRNA/functional studies, the actual effect of this sequence change in this individual is unknown.Therefore, based on the currently available information, it is unclear whether this variant is apathogenic variant or a rare benign variant

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
