GeneDx RCV000118694 SCV000169097 benign not specified 2013-10-14 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.
Genetic Services Laboratory, University of Chicago RCV000118694 SCV000153109 likely benign not specified no assertion criteria provided clinical testing Likely benign based on allele frequency in 1000 Genomes Project or ESP global frequency and its presence in a patient with a rare or unrelated disease phenotype. NOT Sanger confirmed.

One in silico tool predicts a benign outcome for this variant. 5/5 splice prediction tools predict the variant to result in the creation of a cyrpitc splice donor site. However, these predictions have yet to be confirmed by functional studies. This variant was found in 1690/121388 control chromosomes (132 homozygotes), predominantly observed in the Latino subpopulation at a frequency of 0.1302506 (1507/11570). This frequency greatly exceeds the estimated maximal expected allele frequency of a pathogenic TSC1 variant (0.000025), strong evidence that this is likely a benign polymorphism found primarily in the populations of Latino origin. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. Taken together, this variant is classified as benign.
