The original version of this Article contained an error in the title, which was incorrectly given as “APRDX1 mutant allele causes a MMACHC secondary epimutation in cblC patients”. This has now been corrected in both the PDF and HTML versions of the Article to read “A PRDX1 mutant allele causes a MMACHC secondary epimutation in cblC patients”.
