All three deletions included the region chr16:15387380–16198600 (and the genes MPV17L, c16orf45, KIAA0430, NDE1, MYH11, KIAA0866, c16orf63, ABCC1 and MRP6/AbCC6) indicating that a large deletion of this region may be a recurrent schizophrenia risk factor. This evidence concerns the gene MPV17L and schizophrenia.
