ERCC6L2 (Excision Repair Cross-Complementation Group 6 Like 2), also known as RAD26L and as the HElicase mutated in Bone Marrow Failure, HEBO24 is a poorly characterized member of the Sucrose Non-Fermenting 2 (SNF2) family of ATPases25 associated with a distinct bone marrow failure syndrome.24 This evidence concerns the gene ERCC6L2 and Bone marrow hypocellularity.
