- The Human Variome Project (http://www.humanvariomeproject.org) is an international effort aiming to systematically collect and share information on all human genetic variation. The two main pillars of this effort are gene/disease-specific databases and a network of Human Variome Project Country Nodes. The latter are nationwide efforts to document the genomic variation reported within a specific population. The development and successful operation of the Human Variome Project Country Nodes are of utmost importance to the success of Human Variome Project's aims and goals because they not only allow the genetic burden of disease to be quantified in different countries, but also provide diagnosticians and researchers access to an up-to-date resource that will assist them in their daily clinical practice and biomedical research, respectively. Here, we report the discussions and recommendations that resulted from the inaugural meeting of the International Confederation of Countries Advisory Council, held on 12th December 2011, during the 2011 Human Variome Project Beijing Meeting. We discuss the steps necessary to maximize the impact of the Country Node effort for developing regional and country-specific clinical genetics resources and summarize a few well-coordinated genetic data collection initiatives that would serve as paradigms for similar projects.

- We describe 2 children with dysmorphic features, and severe developmental delay presenting with overlapping unbalanced translocations of 9q34.3 and 16p13. Patient #1: A 4 year old African-American female with normal karyotype with a pericentric inversion on one chromosome 9 known to be a benign variant. Low resolution array CGH revealed a single BAC clone loss at 9q34.3 and a single BAC clone gain at 16p13.3, confirmed by FISH. Whole genome SNP array analysis refined these findings, identifying a terminal 1.28 Mb deletion (138,879,862-140,164,310) of 9q34.3 and a terminal 1.62 Mb duplication (45,320-1,621,753) of 16p13.3. Sub-telomeric FISH showed an unbalanced cryptic translocation involving the inverted chromosome 9 and chromosome 16. FISH of the father showed a balanced t(9;16) (q34.3;p13.3) involving the non-inverted chromosome 9, and a pericentric inversion on the normal 9 homologous chromosome. The presence of two rearrangements on chromosome 9, both an unbalanced translocation and a pericentric inversion, indicates recombination between the inverted and derivative 9 homologues from her father. Patient #2: A 1 year old Iraqi-Moroccan female with normal karyotype. Array-CGH identified a 0.56 Mb deletion of 9q34.3 (139,586,637-140,147,760) and an 11.31 Mb duplication of 16p13.3p13.13 (31,010-11,313,519). Maternal FISH showed a balanced t(9;16)(q34.3;p13.13). Both patients present with similar clinical phenotype.
