Cytoonearray-Clinical Diagnostic Tool

Cytoonearray-Clinical Diagnostic Tool

Targeted chromosomal microarray for detecting abnormalities related to micro-deletions and micro-duplications Detects chromosomal abnormalities and familial diseases of fetuses and infants. High-density probe deployment, detecting chromosomal micro-deletions and micro-duplications. In addition to detecting aneuploidy diseases (such as Down's syndrome), CytoOneArray can simultane- ously detect 372 genetic abnormalities (331 diseases and 41 sub-telomeric regions). Emphasis on detecting developmental delays (DD) and intellectual disabilities (ID). Excludes common CNVs in non-specific areas. From analyzing data to the report output, CytoOneArray is easy to operate with our software! [ Array Spec. ] 2 0 Database UCSC hg19 -2 Probe length 57-63 mer only reports disease-related CNVs Disease regions 331 Subtelomeres 41 Disease region 10 - 30 Kb probe resolution 2 0 Total probes 33,255 -2 、 Sample type blood amniotic fluid DNA、tissue Other CMAs report benign CNVs, which may affect clinical interpretation. Missing pathogenic regions may also lead to medical disputes. Application Postnatal Testing • Identifies chromosomal abnormalities from blood DNA • Provides relevant phenotype information • Similar to performing 372 FISH experiments simultaneously Prenatal Testing • Identifies chromosomal abnormalities from amniotic fluid cell DNA • Provides relevant genotype information • Offers a much higher diagnostic yield Process Requisition form & Sample Array Report Informed consent Collection Analysis Explains test results 1 Comparisons with Other Methods FISH Chromosomal Method Karyotyping (Fluorescence in situ microarray Hybridization) Target ChromosomeChromosome fragment Chromosome fragment Resolution 5 - 10 Mb 10 Kb - 100 Kb 10 - 50 Kb To detect specified To detect micro- To detect chromosome Major micro-duplications, duplications and number and large micro-deletions and micro-deletions application physical abnormality structural changes across whole genome Unable to detect Need to know Unable to discriminate Limitation micro-duplications abnormal chromosome balanced chromosome and micro-deletions position prior to test structural changes David Miller et al. The American Journal of Human Genetics 86, 749–764 (2010) Chromosomal microarray analysis should be the first-line genetic test in pregnancies where ultrasound screens uncover signs of fetal abnormalities, according to the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine. ACOG committee opinion, Number 581 (2013) 2 Perfect Support CytoOneArray provides an integrated service system, which starts from array design, to process control of detection, to report generation (Figure A). Figure B depicts an online disease database available to physicians after report generation. This chain of services was designed to assist the diagnosis. A.

No . 7 chr. Abnormal chromosome Analysis Result Interpretation: 1.370 Mb-microdeletion at chromosome 7q11.23 was detected. According to the clinical literature, Williams- Beuren syndrome (WBS) is a contiguous gene deletion syndrome resulting from the deletion on chromosome 7q11.23. Chromosome Ideogram: Copy-number variations (CNVs) are displayed on the corre- sponding locations in the genome. Red regions indicate copy-number losses, and blue regions indicate copy-number gains. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 X Y 4 Disease Name Cytoband OMIM Disease Name A ACMG
