Indications for CMA

Indications for Chromosomal Microarray Analysis and Reasons for Referral

Prenatal Diagnosis, Fetal Medicine, Gynecology:

  • Fetal abnormalities discovered through ultrasound scan
  • Ultrasound abnormality
  • Abnormal maternal serum screen
  • Still birth
  • Miscarriage or Spontaneous abortion
  • Family history of a genetic disease detected by CMA

The American College of Obstetricians and Gynecologists (The College) and the Society for Maternal-Fetal Medicine (SMFM) have recommended Chromosomal Microarray Analysis (CMA) as the first-line genetic test in pregnancies showing fetal abnormalities in an ultrasound scan.

Paediatrics (Neonates and Children with):

  • Mental retardation
  • Developmental delay
  • Multiple congenital anomalies
  • Suspicion of genomic imbalance
  • Autism spectrum disorders
  • Growth delay
  • Speech delay
  • Developmental delay
  • Dysmorphic features
  • Congenital Anomalies
  • Heart Defects
  • Seizures

Cancer:

  • Hematological malignancies
  • Solid Tumors: Renal cell carcinomas

Advanced Genetics:

  • Precise determination of the breakpoints of genomic alterations detected with conventional cytogenetic methods such askaryotype analysis or FISH
  • Suspected whole gene deletion in Mendelian disorders
