About this condition
Complete plasminogen activator inhibitor 1 deficiency (complete PAI-1 deficiency) is a disorder that causes abnormal bleeding. In people with this disorder, bleeding associated with injury can be excessive and last longer than usual.
Individuals with complete PAI-1 deficiency may experience prolonged nosebleeds, excessive bleeding after medical or dental procedures, easy bruising, and significant bleeding into the joints or soft tissues after even a minor injury. Internal bleeding after an injury, especially bleeding around the brain (intracranial hemorrhage), can be life-threatening. Affected females may have excessive bleeding associated with menstruation (menorrhagia) and abnormal bleeding in pregnancy and childbirth.
In addition to bleeding problems, some people with complete PAI-1 deficiency develop scar tissue in the heart (cardiac fibrosis), which can lead to heart failure.

YOUR DNA FILE
What can your DNA file tell you?
Your DNA file only includes the positions your test checked and reported. Consumer DNA kits usually test selected positions. Sequencing files can also leave out positions that were not reported or where the test could not give a result.
A variant missing from your file does not mean you tested negative for it. A ClinVar classification applies to a particular variant and the condition or finding it was reported for. It does not apply to everyone with that gene. An uncertain finding cannot establish a diagnosis.
BioDecode reads supported DNA files on your computer. It cannot fill gaps in your test, diagnose a condition or replace clinical testing.
