GeneDx RCV000118693 SCV000169094 benign not specified 2015-03-04 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 RCV000118693 SCV000153108 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 polymorphism outcome for this variant along with 5/5 splice prediction tools predicting the variant not to have an impact on normal splicing. This variant was found in 9206/121392 control chromosomes (457 homozygotes), predominantly observed in the Latino, (143 homozygotes) subpopulation at a frequency of 0.1558127 (1804/11578). This frequency greatly exceeds the estimated maximal expected allele frequency of a pathogenic TSC1 variant (0.000025), suggesting this is likely a benign polymorphism found primarily in the populations of Latino origin. In addition, multiple clinical diagnostic laboratories classified this variant as Benign. Taken together, this variant is classified as Benign.
Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000118693 SCV000205282 benign not specified 2013-02-21 criteria provided, single submitter clinical testing Ala943Ala in exon 22 of TSC1: This variant is not expected to have clinical sign ificance because it does not alter an amino acid residue and is not located with in the splice consensus sequence. It has been identified in 9.1% (399/4406) of A frican American chromosomes from a broad population by the NHLBI Exome Sequencin g Project (http://evs.gs.washington.edu/EVS; dbSNP rs4962081).
