Test information

Test description

Use long-range PCR and NGS method to detect GLA variations. This test analyzes the GLA gene that has been associated with Fabry disease. Sequencing analysis will be performed on the coding regions of the gene (unless otherwise marked). All analysis is performed utilizing Next Generation Sequencing (NGS) technology. All variants are classified according to ACMG guidelines.

Indications for testing

People with definite symptoms of related genetic diseases.
People with a family history of related genetic disorders.

Condition description

Fabry disease is a lysosomal storage disorder with a wide spectrum of symptoms ranging from mild cases in females, to severe cases in classically affected hemizygous males. Symptoms may include abdominal and joint pain, vascular lesions and corneal abnormalities. Neurological symptoms include autonomic dysfunction and burning sensation or numbness in the extremities. Fabry disease affects an estimated 1 in 40,000 to 1 in 60,000 males. The prevalence is unknown in females.

Test methods and limitations

This test uses Long-range PCR and next-generation sequencing technology. Sequencing is performed on genomic DNA. Direct sequencing of the amplified captured regions was performed on Illumina next generation sequencing (NGS) systems. A base is considered to have sufficient coverage at 20X and an exon is considered fully covered if all coding bases plus three nucleotides of flanking sequence on either side are covered at 20X or more. Low coverage regions, if any, are limited to ~1% or less of the nucleotides in the test unless a pathogenic variant explaining the phenotype is discovered. A list of these regions is available upon request. Alignment to the human reference genome (hg19) is performed and annotated variants are identified in the targeted region. Variants are called at a minimum coverage of 8X and an alternate allele frequency of 20% or higher. Single nucleotide variants (SNVs) meeting internal quality assessment guidelines are confirmed by Sanger sequence analysis for records after results are reported. Indels and SNVs are confirmed by Sanger sequence analysis before reporting at director discretion. This assay cannot detect variants in regions of the exome that are not covered, such as deep intronic, promoter and enhancer regions, areas containing large numbers of tandem repeats, and variants in mitochondrial DNA. Copy number variation (CNV) analysis detects deletions and duplications; in some instances, due to the size of the exons, sequence complexity, or other factors, not all CNVs may be analyzed or may be difficult to detect.

Detailed sample requirements

Dried Blood Spots

Test Details Page
Collection Container(s)	Dried blood spot card
Collection	Follow kit instructions. Briefly, allow blood to saturate the card until indicated areas are filled and blood has soaked through the card. Air dry the card at ambient temperature for at least 3 hours. NBS: Please contact Revvity Omics to request the StepOne^® kit. Gene Sequencing: Please contact Revvity Omics to request the DBS collection kit. For pre-punched DBS: The required minimum is 6 punches
Sample Condition	Follow the instructions provided with the collection set. Store the dried blood at ambient temperature for up to two days. If the specimen cannot be sent as soon as it is dry, the filter paper should be placed in a sealable plastic bag and stored in a refrigerator (≤ 8°C) or preferably in a freezer.
Shipping	Follow kit instructions. Double bag and ship overnight at ambient temperature.

DNA, Isolated

Test Details Page
Collection	Required DNA Quantity by Test Type: Next Generation Sequencing (NGS):* Send >1000 ng total gDNA @ >15 ng/μL. Please ship samples in 10mM Tris. Do not use EDTA. Sanger Sequencing: Send >500 ng total gDNA @ >15 ng/μL (varies by the size of the gene and the variants requested). Non-Sanger Sequencing Tests: Send >500 ng total gDNA @ >15 ng/μL.
Sample Condition	* Required DNA Quality: High molecular weight DNA (>12kb). A260/A280 reading should be ≥ 1.8. A260/230 a ratio range of 1.8 to 2.2. Contact the laboratory for specific amounts if total ng cannot be met.
Shipping	Ship overnight at ambient temperature.
SPECIAL SAMPLE INSTRUCTIONS	Research Laboratories: DNA extracted in research laboratories is not acceptable. Only under exceptional circumstances (e.g., proband not available) will DNA extracted in a research laboratory be accepted for clinical testing. Additional testing (e.g., of other family members) may be required to confirm results. Laboratories outside the United States: Non-US laboratories are not subject to CLIA regulations and will be reviewed on a case-by-case basis. Please call to speak with a laboratory genetic counselor before submitting a DNA sample from any non-CLIA-certified laboratory. Special Notes: If extracted DNA is submitted, information regarding the method used for extraction should be sent along with the sample.

Whole Blood (EDTA)

Test Details Page
Collection Container(s)	EDTA (purple top)
Collection	Infants (< 2-years): 2 to 3 mL; Children (>2-years): 3 to 5 mL; Older children and adults: Minimum 5mL. The blood tube should be inverted several times immediately after blood collection to prevent coagulation.
Sample Condition	Store at ambient temperature. Do not refrigerate or freeze.
Shipping	Ship overnight at ambient temperature ensuring receipt within 5-days of collection.
SPECIAL SAMPLE INSTRUCTIONS	Clotted or hemolyzed samples are not accepted.
