Genetic testing provides answers

Determine whether a child’s developmental challenges are due to a condition caused by a chromosome abnormality. Microarray testing identifies extra or missing chromosomal information in about 15-20% of children with developmental delays and/or birth defects.1


What can Invitae’s microarray analysis for pediatric developmental disorders detect?

  • Size and gene content of copy number variations (CNVs)

  • Regions of homozygosity, which may suggest shared ancestry and an increased risk for autosomal recessive disorders

  • Uniparental disomy, which can indicate an imprinting disorder

When should I order pediatric microarray testing for my patients?

The American College of Medical Genetics, American Academy of Pediatrics, and the American Academy of Neurology recommend chromosomal microarray testing for individuals with one or more of the following:2-4

  • Developmental delays or intellectual disability

  • Congenital anomalies

  • Dysmorphic features

  • Autism and autism spectrum disorders

  • Other potential disorders such as seizures and ADHD

Why is pediatric microarray testing preferred to a karyotype test?

  • Recommended by the American College of Medical Genetics as a first-tier test in lieu of high-resolution karyotyping

  • Doubles the detection rate of chromosomal disorders compared to high-resolution karyotyping and subtelomere FISH combined

  • Higher resolution than karyotyping

  • More comprehensive than karyotyping, which helps prevent unnecessary testing

How long does it take to get results?

  • Microarray results are typically available in 10-12 days, on average, from the time samples are received by Invitae’s lab.

  • G-banded karyotype results are typically available in 12 days, on average, from the time samples are received by Invitae’s lab.

Why choose Invitae’s pediatric microarray?

Superior coverage

Invitae technology provides superior clinically focused, genome-wide coverage.

Comprehensive reports

Invitae’s reports include references to assist in patient counseling and tools for evaluating non-copy number related abnormalities, such as regions of homozygosity.

Expert interpretation

Invitae’s laboratory directors have decades of experience in interpreting microarray results and can assist you in understanding complex results.

Invitae offers buccal swab sample collection

In cases where it is not possible to collect enough blood for an adequate sample, you can opt to collect DNA from the cells on the inside of your patient’s cheek.

Buccal swab collection:

  • Allows clinicians without in-house phlebotomy services to collect samples in-office

  • Frees patients from making a second trip to an off-site draw station

  • Provides patients who are unable to give a blood sample a more comfortable alternative

  • Makes genetic testing more accessible to general practitioners, pediatricians, child neurologists, behavioral pediatricians, and other office-based physicians

Additional tests

Invitae offers a comprehensive test menu that delivers actionable insights for all your patients, whether they are considering pregnancy, pregnant, or already parents.

Proactive cancer screening

More than 9% of healthy adults have a genetic risk of developing cancer. Cancer screening offers healthy adults an opportunity to understand their DNA, assess heritable cancer risk, and take proactive action if necessary.

Carrier screening

80% of children born with genetic disorders have no family history. The American College of Obstetricians and Gynecologists recommends offering carrier screening to all patients of reproductive age.

Pregnancy loss analysis

More than 50% of all early pregnancy losses are due to a fetal chromosomal abnormality. Chromosomal microarray analysis can help identify the cause of recurrent miscarriage.
