Integrated Genetics/Laboratory Corporation of America RCV000588289 SCV000697476 benign not provided 2016-08-23 criteria provided, single submitter clinical testing Variant summary: The TSC2 c.5202T>C (p.Asp1734Asp) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. One in silico tool predicts a polymorphism outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may affect multiple ESE sites. However, these predictions have yet to be confirmed by functional studies. This variant was found in 22671/120414 control chromosomes (3647 homozygotes) at a frequency of 0.1882754, which is approximately 2738 times the estimated maximal expected allele frequency of a pathogenic TSC2 variant (0.0000688), suggesting this variant is likely a benign polymorphism. 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 RCV000118713 SCV000200862 benign not specified 2013-02-21 criteria provided, single submitter clinical testing Asp1734Asp in exon 41 of TSC2: This variant is not expected to have clinical sig nificance because it does not alter an amino acid residue and is not located wit hin the splice consensus sequence. It has been identified in 36.6% (1607/4396) o f African American chromosomes from a broad population by the NHLBI Exome Sequen cing Project (http://evs.gs.washington.edu/EVS; dbSNP rs1748).
