Clinical Genomics Lab,St. Jude Children's Research Hospital RCV000722041 SCV000853218 likely pathogenic Ewing's sarcoma 2017-08-24 criteria provided, single submitter clinical testing This is a splice site alteration in which a C is replaced by an A in intron 4, three nucleotides upstream of exon 5. Classification criteria: PVS1 (Although this alteration is not in a canonical +/- 1 or 2 splice site, examination of the patient's paired tumor transcriptome data revealed that this alteration is associated with abberant splicing and intron retention), PM2.

Invitae RCV000532965 SCV000651882 uncertain significance Tumor susceptibility linked to germline BAP1 mutations 2018-03-21 criteria provided, single submitter clinical testing This sequence change falls in intron 4 of the BAP1 gene. It does not directly change the encoded amino acid sequence of the BAP1 protein, but it affects a nucleotide within the consensus splice site of the intron. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with BAP1-related disease. ClinVar contains an entry for this variant (Variation ID: 472695). Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). 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. 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.
