GeneDx RCV000520072 SCV000617351 pathogenic not provided 2016-01-18 criteria provided, single submitter clinical testing The c.3131+1 G>A splice site variant in the TSC2 gene has been previously reported in association with tuberous sclerosis (Ali et al., 2005; Kwiatkowski et al., 2015; TSC2 LOVD) and is consistent with the diagnosis in this individual. It was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. This pathogenic variant destroys the canonical splice donor site in intron 27, and is expected to cause abnormal gene splicing. Additionally, other canonical splicing variants in intron 27 have been reported in the Human Gene Mutation Database in association with tuberous sclerosis (Stenson et al., 2014).
Invitae RCV001063941 SCV001228812 pathogenic Tuberous sclerosis 2 2019-04-03 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 27 of the TSC2 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in several individuals affected with tuberous sclerosis (PMID: 15595939, 25782670). ClinVar contains an entry for this variant (Variation ID: 49244). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in TSC2 are known to be pathogenic (PMID: 10205261, 17304050). For these reasons, this variant has been classified as Pathogenic.
