Labcorp Genetics (formerly Invitae), Labcorp RCV003613627 SCV004412516 uncertain significance Bloom syndrome 2022-11-04 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change falls in intron 4 of the BLM gene. It does not directly change the encoded amino acid sequence of the BLM protein. It affects a nucleotide within the consensus splice site. This variant has not been reported in the literature in individuals affected with BLM-related conditions. 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. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site.
