Labcorp Genetics (formerly Invitae), Labcorp RCV001379019 SCV001576735 likely pathogenic Hereditary thrombocytopenia and hematological cancer predisposition syndrome associated with RUNX1 2020-07-19 criteria provided, single submitter clinical testing This variant is an in-frame deletion of the genomic region encompassing exon(s) 7 of the RUNX1 gene. It preserves the integrity of the reading frame. This variant has not been reported in the literature in individuals with RUNX1-related conditions. Experimental studies have shown that this deletion (also known as ∆178-241 on the 453 amino acid isoform) results in decreased ability of RUNX1 to interact with transcriptional cofactor, p300, which has been shown to play an important role in RUNX1-dependent transcriptional regulation during differentiation of myeloid cells (PMID: 9606182). This gene is also known as AML1 in the literature. 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.
