Submitter RCV SCV Clinical significance Condition Last evaluated Review status Method Comment
GeneDx RCV000124641 SCV000168074 benign not specified 2013-09-26 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.
Invitae RCV000706456 SCV000835505 uncertain significance Neuronal ceroid lipofuscinosis 2020-02-17 criteria provided, single submitter clinical testing This sequence change affects codon 98 of the CTSD mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the CTSD protein. This variant is present in population databases (rs369373285, ExAC 0.01%). This variant has not been reported in the literature in individuals with CTSD-related disease. ClinVar contains an entry for this variant (Variation ID: 137053). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Department of Pathology and Laboratory Medicine,Sinai Health System RCV001355385 SCV001550259 uncertain significance not provided no assertion criteria provided clinical testing The CTSD p.Thr98Thr variant was not identified in the literature but was identified in dbSNP (ID: rs369373285) and ClinVar (classified as benign by GeneDx and uncertain significance by Invitae). The variant was identified in control databases in 22 of 281814 chromosomes at a frequency of 0.00007807 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: European (non-Finnish) in 21 of 128398 chromosomes (freq: 0.000164) and African in 1 of 24862 chromosomes (freq: 0.00004), but was not observed in the Latino, Ashkenazi Jewish, East Asian, European (Finnish), Other, or South Asian populations. The p.Thr98Thr variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. However, 4 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing and the creation of a new 3' splice site. However, this has not been confirmed by RNA analysis and is not predictive enough to assume pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
