Several diseases have been successfully modeled since the development of induced pluripotent stem cell (iPSC) technology in 2006. Since then, methods for increased reprogramming efficiency and cell culture maintenance have been optimized and many protocols for differentiating stem cell lines have been successfully developed, allowing the generation of several cellular subtypes in vitro. Gene editing technologies have also greatly advanced lately, enhancing disease-specific phenotypes by creating isogenic cell lines, allowing mutations to be corrected in affected samples or inserted in control lines. Neurological disorders have benefited the most from iPSC-disease modeling for its capability for generating disease-relevant cell types in vitro from the central nervous system, such as neurons and glial cells, otherwise only available from post-mortem samples. Patient-specific iPSC-derived neural cells can recapitulate the phenotypes of these diseases and therefore, considerably enrich our understanding of pathogenesis, disease mechanism and facilitate the development of drug screening platforms for novel therapeutic targets. Here, we review the accomplishments and the current progress in human neurological disorders by using iPSC modeling for Alzheimer's disease, Parkinson's disease, Huntington's disease, spinal muscular atrophy, amyotrophic lateral sclerosis, duchenne muscular dystrophy, schizophrenia and autism spectrum disorders, which include Timothy syndrome, Fragile X syndrome, Angelman syndrome, Prader-Willi syndrome, Phelan-McDermid, Rett syndrome as well as Nonsyndromic Autism.

Rob(15; 22) is rare and account for only 0.6% of all Robertsonian translocations. We describe a case with rob(15;22) in which the phenotype includes generalized hypotonia, respiratory distress, tent shaped upper lips, hyporeflexia and single umbilical artery. Chromosome analysis with peripheral blood was performed, while the karyotype was interpreted as 45,XX,der(15;22)(q10;q10). In Prader-Willi/Angelman Syndrome FISH studies, deletion of the SNRPN gene was not observed, but deletion of 15p11.2 was noted. Prader-Willi/Angelman Syndrome methylation-specific polymerase chain reaction and chromosomal microarrays showed negative findings. Molecular studies associated with spinal muscular atrophy and progressive muscular dystrophy also showed negative findings. We suggest that rob(15;22) and deletion of 15p11.2 could be related to clinical presentation like this case.
