GeneDx RCV000189943 SCV000243610 benign not specified 2016-06-08 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Illumina Clinical Services Laboratory,Illumina RCV000043179 SCV000395675 likely 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 likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000189943 SCV000918329 likely benign not specified 2018-03-17 criteria provided, single submitter clinical testing Variant summary: TSC2 c.5116C>T (p.Arg1706Cys) results in a non-conservative amino acid change located in the Rap GTPase activating protein domain of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The observed variant frequency is approximately 4-fold of the estimated maximal expected allele frequency for a pathogenic variant in TSC2 causing Tuberous Sclerosis Complex phenotype (6.9e-05), strongly suggesting that the variant is benign. The variant, c.5116C>T, has been reported in the literature in individuals affected with Tuberous Sclerosis Complex (Jozwiak_2014). These report(s) do not provide unequivocal conclusions about association of the variant with Tuberous Sclerosis Complex. A functional study, Hoogeveen-Westerveld_2012, found the variant to act comparable to wild type protein and classified as probably neutral. An internal specimen reports the variant to co-occur with pathogenic FLCN, c.927_954dup28. Multiple ClinVar submissions from clinical diagnostic laboratories (evaluation after 2014) cites the variant as "likely benign/benign." Based on the evidence outlined above, the variant was classified as likely benign.
