the autism spectrum disorders (asds) are common neurodevelopmental disorders estimated to affect 1 in 88 children. asd is a complex condition, result of genetic, epigenetic and environmental factors. however, genetic comopnent seems to play an important role. the loss/gain of 1kb and more nucleotides, copy number variation (cnv), is the significant genetic factor in the etiology of asd. the cnv...
Comprehensive chromosome analysis techniques such as metaphase-Comparative Genomic Hybridisation (CGH) and array-CGH are available for single-cell analysis. However, while metaphase-CGH and BAC array-CGH have been widely used for Preimplantation Genetic Diagnosis, oligonucleotide array-CGH has not been used in an extensive way. A comparison between oligonucleotide array-CGH and metaphase-CGH ha...

Comparative genomic hybridization (CGH) microarrays have been used to determine copy number variations (CNVs) and their effects on complex diseases. Detection of absolute CNVs independent of genomic variants of an arbitrary reference sample has been a critical issue in CGH array experiments. Whole genome analysis using massively parallel sequencing with multiple ultra-high resolution CGH arrays...
background: disorders of sex development (dsds) belong to uncommon pathologies and result from abnormalities during gonadal determination and differentiation. various gene mutations involved in gonadal determination and differentiation have been associated with gonadal dysgenesis. despite advances in exploration of genes and mechanisms involved in sex disorders, most children with severe 46,xy ...
BACKGROUND Array Comparative Genomic Hybridization (array CGH) is increasingly applied on DNA obtained from formalin-fixed paraffin-embedded (FFPE) tissue, but in a proportion of cases this type of DNA is unsuitable. Due to the high experimental costs of array CGH and unreliable methods for DNA quality testing, better prediction methods are needed. The aim of this study was to accurately determ...

MOTIVATION Array-CGH can be used to determine DNA copy number, imbalances in which are a fundamental factor in the genesis and progression of tumors. The discovery of classes with similar patterns of array-CGH profiles therefore adds to our understanding of cancer and the treatment of patients. Various input data representations for array-CGH, dissimilarity measures between tumor samples and cl...
بیماری سرطان خون پرومیلوسیتیک حاد (apl) با جابجایی کروموزومی t(15;17) همراه است که منجر به ایجاد پروتئین pml-rara می شود. بررسی مدلهای حیوانی نشان داده اند که اگرچه در این بیماری وجود این پروتئین الحاقی ضروری است ولی به تنهایی برای توسعه بیماری کافی نیست. با مطالعه آرایه های بیماران و مدلهای حیوانی apl نواحی کروموزومی که غالبا" دچار حذف یا تکثیر می شوند انتخاب شدند. 11 ناحیه ژنی شامل tp53، cmyc...
