Haploinsufficiency of the RPS19 gene is known to cause Diamond-Blackfan anemia, other features in this patient are likely due to the deletion of other candidate genes such as PAFAH1B3, ERF, LIPE and GSK3A.<h4>Conclusion</h4>The deletion detected in our patient overlapped and was significantly smaller than the ones previously reported, which offered the opportunity to further define the critical region for this proposed contiguous gene deletion syndrome. Here, ERF is linked to Diamond-Blackfan anemia.
