Ambry Genetics | RCV000565556 | SCV000675736 | uncertain significance | Hereditary cancer-predisposing syndrome | 2016-07-25 | criteria provided, single submitter | clinical testing | The c.5197_5211del15 variant (also known as p.T1733_P1737del) is located in coding exon 40 of the TSC2 gene. This variant results from an in-frame deletion of 15 nucleotides (ACCGATATCTACCCC) at positions 5197 to 5211. This results in the in-frame deletion of 5 residues between codons 1733 and 1737. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6497 samples (12994 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.006% (greater than 20000 alleles tested) in our clinical cohort. This amino acid region is well conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
