RCV001307933 | SCV001497361 | uncertain significance | Retinoblastoma | 2020-04-28 | criteria provided, single submitter | clinical testing | 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. A similar copy number gain has been observed in individual(s) with RB1-related conditions (PMID: 19280657). This variant results in a copy number gain of the genomic region encompassing exon(s) 18-27 of the RB1 gene. The 5' boundary is likely confined to intron 17. The 3' end of this event is unknown as it extends beyond the assayed region for this gene and therefore may encompass additional genes. As the precise location of this event is unknown, it may be in tandem or it may be located elsewhere in the genome. |
