Cytogenic variations are known to cause a broad range of developmental disorders, primarily neurodevelopmental and congenital anomalies.
Chromosomal microarray analysis (CMA) is recommended for analyzing cytogenic variations in patients suffering for unexplained developmental delays, intellectual disabilities, autism spectrum disorders, and/or multiple congenital malformations.
CENTOGENE’s microarray-based solution – CentoArray – enables the genome-wide detection of known novel structural aberrations, copy number variations (CNVs), chromosomal imbalances, regions exhibiting loss/absence of heterozygosity (LOH), uniparental isodisomy (UPD), and mosaicism.
Why Choose CentoArray?
Built on the latest genetic and medical insights
Covering more than 4,800 cytogenetic relevant genes with exon level resolution
Short turnaround time
high resolution and broad coverage
Optimized probe spacing, focusing on exonic regions to provide the best cytogenetic disease variant coverage
Platform designed to represent latest clinical and genetic insights with more than 4,800 cytogenic relevant genes based on ClinGen, DDG2P, ClinVar, PharmGKB, NHGRI-EBI, and GWAS database
Quality analysis with a wide range of sample types
Delivering high-quality analysis via a wide range of samples including CentoCard®, EDTA blood, ready to use DNA, buccal swab, chronic villi, and amniotic fluid
- As a first-step analysis for cases of unexplained developmental delays, intellectual disabilities, autism spectrum disorders, and/or multiple congenital malformations
- For deletion/duplication analysis of extremely large genes where gross deletions involving large segments of genes, flanking intergenic regions, or neighboring genes are frequently reported
- To diagnose uniparental disomy (UPD) and regions exhibiting loss/absence of heterozygosity (LOH)
- In conjunction with whole exome sequencing (CentoXome) to complement large CNVs. CentoArray can be ordered either as a step-wise analysis after CentoXome or together as a single-step approach
- For prenatal testing to help determine a cause of ultrasound-detected abnormalities via CentoArray Prenatal
