Invitae | RCV000707792 | SCV000836902 | pathogenic | Tuberous sclerosis 2 | 2018-03-27 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exons 27-42 of the TSC2 gene. The 5' boundary is likely confined to intron 26. The 3' end of this event is unknown as it extends through the termination codon beyond the assayed region for this gene and may encompass additional genes. While this deletion is not anticipated to result in nonsense mediated decay, it is expected to create a truncated protein product or disrupt mRNA translation. This variant has not been reported in the literature in individuals with TSC2-related disease. Similar exon level deletions that extend through the last exon of TSC2 gene have been determined to be pathogenic (PMID: 11281455, 17287951, 22169896). This suggests that deletion of this region of the TSC2 protein is causative of disease. For these reasons, this variant has been classified as Pathogenic. |
