Test Overview
Test Methodology

Exon 4 of the PAI-1 (SERPINE1) gene is amplified using specific primers, and bidirectionally sequenced using a fluorescent method.

Test Usage

Analysis for the presence of the c.699_700dupTA frameshift mutation in the PAI-1 (SERPINE1) gene, in patients with clinical features consistent with Plasminogen Activator Inhibitor-1 (PAI-1) deficiency.

Reference Range *

Interpretive report provided.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

This assay will not detect large deletions in the PAI-1 (SERPINE1) gene or intronic mutations outside the region sequenced in the PAI-1 (SERPINE1) gene. This assay is designed specifically to detect a c.699_700dupTA frameshift mutation in the PAI-1 (SERPINE1) gene, and other mutations in this gene may not be detected. Mutations in other genes associated with the aforementioned syndrome will not be detected.

Hemolyzed blood sample. Fresh tissue (POC) or paraffin embedded specimens are not acceptable.
Additional Information

The c.699_700dupTA frameshift mutation results in the premature formation of a stop codon that causes the truncation of the PAI-1 protein and is associated with PAI-1 deficiency. By ordering this test the clinician acknowledges that informed consent has been obtained from the patient as required by applicable state or federal laws and the ordering clinician has authorization from the patient permitting MLabs to report the test results to the ordering clinician. Test includes medical geneticist interpretation of results billed as a separate additional charge. This test is not available without interpretation.
