A Familial 4q12 Deletion Involving KIT Gene Causes Piebaldism
T Piebaldism is a rare, autosomal dominant disorder characterized by the congenital absence of melanocytes in affected areas of
the skin and hair. We report on a familial 4q12 deletion that involves
the KIT gene and causes piebaldism in affected individuals. Wholegenome genotyping analysis of the proband using HumanCytoSNP12v2.1 BeadChips (Illumina Inc., San Diego, CA, USA, revealed a 1.34-Mb
microduplication of 1q21.1q21.2 and a 2.7-Mb microdeletion of 4q12.
The analysis of the parents confirmed the paternal origin of the 4q12
microdeletion. The clinical and molecular findings in the proband and
his affected relatives showed that the 2.7-Mb 4q12 microdeletion, the
smallest microdeletion reported to date, causes isolated piebaldism
due to the loss of the KIT gene

Genome editing in medicine: tools and challenges
Studies which seek fundamental, thorough knowledge of biological processes, and continuous advancement in natural sciences and biotechnology enable the establishment of molecular strategies and tools to treat disorders caused by genetic mutations. Over the years biological therapy evolved from using stem cells and viral vectors to RNA therapy and testing different genome editing tools as promising gene therapy agents. These genome editing technologies (Zinc finger nucleases, TAL effector nucleases), specifically CRISPR-Cas system, revolutionized the field of genetic engineering and is widely applied to create cell and animal models for various hereditary, infectious human diseases and cancer, to analyze and understand the molecular and cellular base of pathogenesis, to find potential drug/treatment targets, to eliminate pathogenic DNA changes in various medical conditions and to create future “precise medication”. Although different concerning factors, such as precise system delivery to the target cells, efficacy and accuracy of editing process, different approaches of making the DNA changes as well as worrying bioethical issues remain, the importance of genome editing technologies in medicine is undeniable. The future of innovative genome editing approach and strategies to treat diseases is complicated but interesting and exciting at once for all related parties – researchers, clinicians, and patients
Genotype and phenotype data analysis and visualization
In this paper, we present a comparative analysis of hierarchical clustering and multidimensional scaling methods for genotype and phenotype data analysis. Fisher's exact test was applied to determinate dependencies between congenital anomalies. In order to determine the relationship between the dependences of congenital anomalies, deformations, these systems’ micro anomalies and congenital anomalies associated with orofacial clefs, the Spearman and Kendall correlation coefficients were applied. It has been detected which methods are better for genetic data visualization
