CAMT, syndromic thrombocytopenia, and other syndromic thrombocytopenias
| Subtype | Approximate % of patients | Chromosome location | Gene product/locus | Exons |

MECOM (MDS1 and EVI1 Complex Locus) variants can be associated with variable hematological features ranging from isolated thrombocytopenia to global BM failure and leukemia.
