Minimal Critical Region in the two groups of patients.
<p>Column 1, the location of the MCR that follows the rules of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0016623#pone-0016623-t004" target="_blank">tables 4</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0016623#pone-0016623-t005" target="_blank">5</a>; the figures in brackets and in bold are the ratios of the amplified regions.

aCGH karyogram of patient t-8 and MCR delineation of RUNX1.
<p>Aâ=âA del (7q) and trisomy 13 are obvious. Cryptic deletions from 21q22.1 (corresponding to RUNX1) and from Xp11.4, that are smaller than 60kb, are nullosomic. On 22q11, the loss is a constitutive CNV of GGT1. Bâ=âA UCSC map (build 18) of the RUNX1 gene. Câ=âThe deletions of RUNX in four patients at the molecular level are labeled in orange and the smallest in red. The location of the breakpoints are indicated at the ends of the colored lines. Patient t-8 exhibits a homozygous 590 Kb deletion that encompassed the entire RUNX1 gene and could have occurred by an acquired isodisomy. Patient t-11 had the smallest deletion (40Kb) that was internal to RUNX1; t-29 had a deletion limited to RUNX1.</p
