Invitae RCV000475988 SCV000564003 likely pathogenic Retinoblastoma 2016-11-07 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exons 14-17 of the RB1 gene. This leads to an in-frame deletion, preserving the integrity of the reading frame. This variant has been reported in an individual affected with retinoblastoma with (PMID: 16127685). An in-frame deletion of exon 14 deletion has also been observed in two members of a family affected with retinoblastoma (PMID:, 21654082). This variant removes a portion of the A-box domain of the "pocket" of RB1 (AAs 380-785) (PMID: 9495340, 12502741), which is critical for RB1 interactions with downstream factors such as E2F (PMID: 8756645, 12502741, 1534305). In summary, this variant is a rare in-frame deletion that is present in a retinoblastoma patient and disrupts an essential domain in the RB1 protein. This evidence indicates that the variant is pathogenic, but additional data is needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
