What does a microarray test for?

A microarray is the recommended first line genetic test for developmental delay (DD), intellectual disability (ID) and autism spectrum disorders (ASD)*. CMA however, does not identify fragile X syndrome (FXS), a common cause of intellectual disability.

Why is microarray analysis important?

The microarrays have become important because they are easier to use, do not require large-scale DNA sequencing and allow the parallel quantification of thousands of genes from multiple samples.

How long does a microarray test take?

How long does it take to get results? Microarray results are typically available in 7-8 days from the time samples are received by Invitae’s lab. G-banded karyotype analysis offers detection of numeric chromosome abnormalities, balanced and unbalanced chromosome rearrangements, and polyploidy in 10-12 days on average.

What does a microarray not tell you?

This test does not check for every possible genetic disease or give information about a specific gene.

Can microarray detect Williams Syndrome?

It uses a fluorescent marker to determine if the genes critical to Williams syndrome are present or not. A chromosomal microarray uses millions of markers to determine if there are missing pieces or extra pieces of DNA anywhere in the person’s chromosomes.

Why is microarray performed?

A microarray is a laboratory tool used to detect the expression of thousands of genes at the same time. The DNA molecules attached to each slide act as probes to detect gene expression, which is also known as the transcriptome or the set of messenger RNA (mRNA) transcripts expressed by a group of genes. …

Under what applications are microarrays useful?

It helps especially in the identification of single-nucleotide polymorphisms (SNPs) and mutations, classification of tumors, identification of target genes of tumor suppressors, identification of cancer biomarkers, identification of genes associated with chemoresistance, and drug discovery.

How much does a microarray cost?

A targeted DNA microarray runs from $10 to $100 per sample, says Schena, whereas “the whole human genome is typically $100 [to] $1,000 per sample.” (Targeting strategies are also available for NGS, to avoid the costs incurred by whole-genome sequencing, but they also add both cost and time.)

Can microarray detect Turner syndrome?

Prenatal diagnosis may indicate a karyotype consistent with a diagnosis of Turner syndrome; however, the phenotype of the individual cannot be predicted based on the chorionic villus or amniotic fluid cell karyotype, FISH, or microarray results.

What treatments are available for Williams syndrome?

What are the treatment options for Williams syndrome?

ballooning or stenting of blood vessels.
patching of the aorta, coronary arteries or pulmonary arteries.
a hybrid approach that involves a collaboration between the interventional cardiologist and surgeon to place stents in difficult-to-reach blood vessels.

What does microarray test for?

“Microarray” refers to a microchip-based testing platform that allows high-volume, automated analysis of many pieces of DNA at once. CMA chips use labels or probes that bond to specific chromosome regions. Computer analysis is used to compare a patient’s genetic material to that of a reference sample.

What information does a microarray tell you?

A microarray is a chip holding several probes representing sequences of the genome of the organism/cell you re using. You may be interested in which genes are expressed in your cell under a particular condition: stress, mutation and so on.

How long for microarray results?

What does microarray analysis mean?

Microarray analysis is a method that makes use of gene chips to which thousands of different mRNAs can bind and be quantified.
