Invitae RCV000816627 SCV000957144 likely pathogenic Fanconi anemia 2018-08-13 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exons 8-14 of the FANCL gene. The 5' boundary is likely confined to intron 7. 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 FANCL-related disease. This variant disrupts a large part of the double-RWD (DRWD) domain of the FANCL protein that is required for the interaction with its substrate, the FANCD2-FANCI complex. In addition, this variant deletes the C-terminal RING domain of the FANCL protein, which selectively recruits the E2-ubiquitin conjugating enzyme, UBE2T, for the mono-ubiquitination of the D2/I complex (PMID: 20154706, 26149689). This indicates that this region is important for protein function. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
