Bayat (2012, 22448145) Approx 300b deletion /?duplication/rearrangement, Complex genomic MARS2 rearrangements identified in 54 affected French-Canadian cases belonging to 38 families with a mean age of onset of 24.4 (2–59). Lots of in vivo studies. No HGMD/Pubmed reports of MARS2 rearrangements since this paper, but probably inst being widely tested and if so, large rearrangements aren't particularly amenable to ngs
