The current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in SEC61A1 cause disease. The boundaries of this event are unknown as they extend beyond the assayed region for this gene and therefore may encompass additional genes. This variant has not been reported in the literature in individuals with SEC61A1-related conditions.

A gross deletion of the genomic region encompassing the full coding sequence of the GATA2 gene has been identified. Loss-of-function variants in GATA2 are known to be pathogenic (PMID: 21670465, 23223431). The boundaries of this event are unknown as they extend beyond the assayed region for this gene and therefore may encompass additional genes. Isolated whole-gene myelodysplastic syndrome and/or acute myeloid leukemia of GATA2 have not been reported in the literature.
