Variant summary: The PTCH1 c.4080C>T (p.Ser1360Ser) variant causes a synonymous change involving a non-conserved nucleotide with 5/5 splice prediction tools predicting no significant affect on splicing. The variant of interest was observed in the large, broad control population, ExAC, with an allele frequency of 468/116042 (1/247, 2 homozygotes), which significantly exceeds the expected allele frequency for a pathogenic PTCH1 variant of 1/58479, suggesting this variant is likely a benign polymorphism. In addition, multiple clinical diagnostic laboratories have cited the variant as "benign." Therefore, the variant of interest has been classified as Benign. -

Gorlin syndrome Benign:3
- -
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. -
- -
Hereditary cancer-predisposing syndrome Benign:2
- -
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. -
