A Novel 2.3 Mb Microduplication of 9q34.3 Inserted into 19q13.4 in a Patient with Learning Disabilities

Figure 3

Location and extent of 9q34 duplications. UCSC Genome Browser (March 2006 (hg18) assembly) view of the chromosomal region 9q34.13-q34.3 (chr9:134,776,210-140,171,337) is shown, together with Refseq, OMIM, and GAD genes. The bottom panel shows the location and extent of the 9q34.3-qter region of the patient described here, and of other cases reported in the literature. Note: the region highlighted in yellow is the ~2.3 Mb region duplicated in our case, and the thicker green block represents the triplicated region reported by Gijsbers et al. [8].
