Abstract Inversions play an important role in disease and evolution but are difficult to characterize because their breakpoints map to large repeats. We increased by six-fold the number (n = 1,069) of previously reported great ape inversions using Strand-seq and long-read sequencing. We find that the X chromosome is most enriched (2.5-fold) for inversions based on its size and duplication content. -

Morton1,2,5,20,21,* In this exciting era of ‘‘next-gen cytogenetics,’’ integrating genomic sequencing into the prenatal diagnostic setting is possible within an actionable time frame and can provide precise delineation of balanced chromosomal rearrangements at the nucleotide level. Given the increased risk of congenital abnormalities in newborns with de novo balanced chromosomal rearrangements, comprehensive interpre- tation of breakpoints could substantially improve prediction of phenotypic outcomes and support perinatal medical care. Herein, we present and evaluate sequencing results of balanced chromosomal rearrangements in ten prenatal subjects with respect to the location of regulatory chromatin domains (topologically associated domains [TADs]). -

Lluis Companys 23, Barcelona 08010, Spain *Corresponding authors: Luciano Di Croce ([email protected]) Sergi Aranda ([email protected]) 1 GRAPHICAL ABSTRACT Chromatin-bound proteins regulate gene expression, replicate and repair DNA, and transmit epigenetic information. Several human diseases are highly influenced by alterations in the chromatin- bound proteome. Thus, biochemical approaches for the systematic characterization of the chromatome could contribute to identifying new regulators of cellular functionality, including those that are relevant to human disorders. 2 SUMMARY Chromatin-bound proteins underlie several fundamental cellular functions, such as control of gene expression and the faithful transmission of genetic and epigenetic information. Components of the chromatin proteome (the “chromatome”) are essential in human life, and mutations in chromatin-bound proteins are frequently drivers of human diseases, such as cancer. Proteomic characterization of chromatin and de novo identification of chromatin interactors could thus reveal important and perhaps unexpected players implicated in human physiology and disease. Recently, intensive research efforts have focused on developing strategies to characterize the chromatome composition. In this review, we provide an overview of the dynamic composition of the chromatome, highlight the importance of its alterations as a driving force in human disease (and particularly in cancer), and discuss the different approaches to systematically characterize the chromatin-bound proteome in a global manner. -

Gutachter Prof. Dr. Martin Vingron 2. Gutachter: Prof. Dr. Peter N. Robinson 3. Gutachter: Christopher J. Mungall, Ph.D. Tag der Disputation: 16.05.2013 Preface This thesis presents research work on novel computational approaches to investigate and characterise the association between genes and pheno- typic abnormalities. It demonstrates methods for organisation, integra- tion, and mining of phenotype data in the field of genetics, with special application to human genetics. Here I will describe the parts of this the- sis that have been published in peer-reviewed journals. Often in modern science different people from different institutions contribute to research projects. The same is true for this thesis, and thus I will itemise who was responsible for specific sub-projects. In chapter 2, a new method for associating genes to phenotypes by means of protein-protein-interaction networks is described. I present a strategy to organise disease data and show how this can be used to link diseases to the corresponding genes. I show that global network distance measure in interaction networks of proteins is well suited for investigat- ing genotype-phenotype associations. This work has been published in 2008 in the American Journal of Human Genetics. My contribution here was to plan the project, implement the software, and finally test and evaluate the method on human genetics data; the implementation part was done in close collaboration with Sebastian Bauer. -

10Q11.22Q11.23 Deletions and Microdeletions
10q11.22q11.23 Deletions and Microdeletions rarechromo.org Genetic information Genetic 10q11.22q11.23 microdeletions A 10q11.2q11.23 microdeletion is a rare genetic condition caused by the loss of a small piece of genetic material from one of the body’s 46 chromosomes – chromosome 10. For typical development, chromosomes should contain the expected amount of genetic material. Like many other chromosome disorders, having a missing piece of chromosome 10 may affect a child’s health, development and intellectual abilities. The symptoms observed in people with a 10q11.22q10.23 microdeletion are variable and depend on a number of factors including what and how much genetic material is missing. Background on chromosomes Our bodies are made up of many different types of cells, almost all of which contain the same chromosomes. Each chromosome consists of DNA that codes for our genes. Genes can be thought of as individual instructions that tell the body how to develop, grow and function. Chromosomes come in pairs with one member of each chromosome pair being inherited from each parent. Most of our cells have 23 pairs of chromosomes (a total of 46) as shown in this image. Eggs and sperm, however, have 23 unpaired chromosomes. When an egg and sperm join together at conception, the chromosomes pair up to make a total of 46. Chromosome pairs are numbered 1 to 22 Chromosomes pairs 1-22, X and Y (male) and the 23rd pair comprises the sex Chromosome pair 10 is circled in red chromosomes that determine biological sex. They can be viewed under a microscope and arranged roughly according to size as the image shows. -

Copy Number Determination of the Gene for the Human Pancreatic
Shebanits et al. BMC Biotechnology (2019) 19:31 https://doi.org/10.1186/s12896-019-0523-9 RESEARCH ARTICLE Open Access Copy number determination of the gene for the human pancreatic polypeptide receptor NPY4R using read depth analysis and droplet digital PCR Kateryna Shebanits1 , Torsten Günther2, Anna C. V. Johansson3, Khurram Maqbool4, Lars Feuk4, Mattias Jakobsson2,5 and Dan Larhammar1* Abstract Background: Copy number variation (CNV) plays an important role in human genetic diversity and has been associated with multiple complex disorders. Here we investigate a CNV on chromosome 10q11.22 that spans NPY4R, the gene for the appetite-regulating pancreatic polypeptide receptor Y4. This genomic region has been challenging to map due to multiple repeated elements and its precise organization has not yet been resolved. Previous studies using microarrays were interpreted to show that the most common copy number was 2 per genome. Results: We have investigated 18 individuals from the 1000 Genomes project using the well-established method of read depth analysis and the new droplet digital PCR (ddPCR) method. We find that the most common copy number for NPY4R is 4. The estimated number of copies ranged from three to seven based on read depth analyses with Control- FREEC and CNVnator, and from four to seven based on ddPCR. We suggest that the difference between our results and those published previously can be explained by methodological differences such as reference gene choice, data normalization and method reliability. Three high-quality archaic human genomes (two Neanderthal and one Denisova) display four copies of the NPY4R gene indicating that a duplication occurred prior to the human-Neanderthal/Denisova split.
