ACTIA

Precision in diagnosis, including the identification of disease subtypes, directly influences treatment and patient outcomes. Understanding of pathology at a molecular level is critical for identification of many diseases and their subtypes.

Presenting ACTIA from MedGenome, delivering ACTIONABLE insights to enable happier outcomes. Actia provides an end-to-end integrated solution to clinical genomics in India and is highly focussed on the Indian population.

What is Chromosomal Microarray (CMA)?

  • It is a microchip-based testing platform that allows automated analysis of many pieces of DNA at once
  • CMA chips use probes that hybridize with specific chromosomal regions to detect copy number variations (CNV)
  • Its analysis offers the capacity to examine the whole human genome in a single chip with high resolution
  • It offers a combination of CNV and SNPs

Types of CMA

Xon array

  • Provides very high-resolution DNA copy number analysis to detect gains and losses at xon level. Also detects loss of heterozygosity (LOH), regions identical-by-descent, and uniparental isodisomy (UPD) on a single array
  • Extensive coverage for 453,076 xons is 17974 genes with increased sensitivity and specificity in 7000 clinically relevant genes

750K array

  • Offers comprehensive gene-level coverage for known constitutional genes on a single array
  • Ideas for investigation of neurological disorder

Optima array

  • Ideal for genetic analysis of product of conception (POC)
  • Aneuploidy analysis

Why Chromosomal Microarray (CMA)?

  • First-tier test* for individuals with:
    • Developmental disabilities
    • Autism spectrum disorders
    • Multiple congenital anomalies
    • Mental Retardation
  • For individuals with seizures and other developmental problems for which a chromosomal basis is suspected
  • Detection of CNV’s at single xon level ensuring diagnosis of single gene diseases too.

Why Actia CMA is Better?

  • Higher Resolution#
  • Nearly double diagnostic yield#
  • Multiplexing/Throughput is possible
  • Detection of Maternal Cell Contamination
  • Detection of Uniparental Disomy
