{slide=Candidates for Testing}
Patients who want to prepare for prenatal/pre-implantation diagnosis and for predictive testing for individuals at risk of inheriting an already known pathogenic variant with detection of mosaicism for at least 3-5% of the variant allele fraction (VAF)

Please find specimen requirement specifications above.
All submitted specimens must be sent at room temperature. DO NOT ship on ice.
Specimens must be packaged to prevent breakage and absorbent material must be included in the package to absorb liquids in the event that breakage occurs. Also, the package must be shipped in double watertight containers (e.g. a specimen pouch + the shipping company’s diagnostic envelope).
To request a sample collection kit, please click here or email medgenomics@uabmc.edu to complete the specimen request form.
Please contact the MGL (via email at medgenomics@uabmc.edu, or via phone at 205-934-5562) prior to sample shipment and provide us with the date of shipment and tracking number of the package so that we can better ensure receipt of the samples.

About
{slide=Test Description}We offer targeted detection of a previously characterized pathogenic variant within the family. From a fresh EDTA blood sample, DNA is extracted directly and the target region is amplified and analyzed using Next-Generation sequencing-based targeted testing with deep coverage of the alleles. This analysis provides detection of mosaicism for a known variant present in at least 3-5% variant allele fraction (or lower, depending on the gene analyzed). To offer this testing service, the proband’s variant must be identified by our laboratory before testing relatives.
