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]

Benign, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Jan 13, 2018 | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. - |

Benign, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | May 24, 2016 | Variant summary: The PTCH1 c.1665T>C (p.Asn555Asn) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. One in silico tool predicts a polymorphism outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may affect ESE site of SRp55. This variant was found in 12470/115592 control chromosomes (719 homozygotes) at a frequency of 0.1078794, which is approximately 6295 times the estimated maximal allele frequency of a pathogenic PTCH1 variant (0.0000171), suggesting this variant is a benign polymorphism. This variant has been reported in multiple affected individuals in co-occurrence with different pathogenic variants (Pastorino_Human_Mutation_2005), further supporting the benign classification. In addition, another clinical diagnostic laboratory classified this variant as benign. Taken together, this variant is classified as benign. - |
