Labcorp Genetics (formerly Invitae), Labcorp RCV002745908 SCV003013500 likely pathogenic Fanconi anemia 2022-04-07 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 4 of the FANCA gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in FANCA are known to be pathogenic (PMID: 19367192). This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individual(s) with Fanconi anemia (PMID: 29098741). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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.
