Collect

Collect whole blood in a purple top (EDTA) tube (preferred). Extracted DNA and saliva are also acceptable.

Specimen Preparation

Please provide detailed clinical history and features. For more information contact the lab at 6-1447 or by sending an email to DGDGeneticCounselor@chop.edu.

Unacceptable Conditions

Heparinized specimens, severely hemolyzed specimens, frozen, clotted or possibly commingled specimens, blood in non-sterile or leaky containers, mislabeled or inappropriately labeled specimens.

Storage/Transport Temperature

For CHOP Phlebotomy: Samples can be collected throughout the week. Samples collected on weekends or holidays are held in Central Labs and sent to the Genomic Diagnostic Lab the following business day. 

For External Clients: Refrigerate sample until shipment. Send the sample at room temperature with overnight delivery for receipt Monday through Friday, optimally within 24 hours of collection.

Please contact the lab (267-426-1447) with questions regarding non-blood specimens.

Volume Required

2-3 mL of blood or 3 ug of DNA with a concentration of at least 50 ng/ul

Minimum Required

1 mL of whole blood

Phlebotomy Draw

Yes

Clinical Features

The Hereditary Breast/Gyn Cancer Panel includes sequence and copy number analyses of the genes associated with a hereditary predisposition to breast, ovarian, and/or endometrial cancer. 

Performing Lab

Division of Genomic Diagnostics

Performed

Monday-Friday 9:00am - 4:00pm

Reported

28 days

Detection Rate

The clinical sensitivity for comprehensive sequencing and copy number analysis is dependent on the patient's clinical features.

Utility

The clinical utility of the assay is to support a clinical diagnosis of the disease, facilitate genetic counseling, and assess the risk to other first degree relatives and to facilitate testing of at-risk family members.

Test Notes

Genomic DNA was extracted from patient tissue following standard DNA extraction protocols. Whole genome sequencing was performed on the Illumina NovaSeq 6000 platform using the Illumina DNA PCR-Free Library Prep with 150bp paired-end reads. Mapping and analysis were based on the GRCh38 reference sequence. Sequencing data was processed using the Dragen pipeline (Illumina) to call both sequence and copy number variants.

Molecular Testing Notes

The Hereditary Breast/Gyn Cancer Panel includes sequence and copy number analyses of the following genes: ATM, BARD1, BRCA1, BRCA2, BRIP1, CDH1, CHEK2, EPCAM**, ERCC4, FANCA, ITK, MEN1, MLH1, MSH2, MSH6, MUTYH, NBN, NF1, PALB2, PMS2, PTEN, RAD50, RAD51C, RAD51D, SMARCA4, STK11, TP53, and WRN.
