Illumina Laboratory Services, Illumina	RCV000042691	SCV000395676	benign	Tuberous sclerosis syndrome	2018-01-13	criteria provided, single submitter	clinical testing	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.

The variant of interest was observed in the large, broad control population, ExAC, with an allele frequency of 24902/120464 (3635 homozygotes, 1/4), which significantly exceeds the estimated maximal expected allele frequency for a pathogenic TSC2 variant of 1/14534 (0.0000688), suggesting this variant is likely a benign polymorphism. In addition, multiple reputable clinical laboratories cite the variant as "benign/likely benign." Therefore, the variant of interest has been classified as Benign.
