Test ID: F10NG    
Factor X Deficiency, F10 Gene, Next-Generation Sequencing, Varies

Useful For Suggests clinical disorders or settings where the test may be helpful

Genetic confirmation of a factor X deficiency diagnosis with the identification of a known or suspected pathogenic alterations in the F10 gene


Carrier testing for close family members of an individual with a factor X deficiency diagnosis


This test is not intended for prenatal diagnosis.

Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request

This test detects pathogenic alterations within the F10 gene to delineate the underlying molecular defect in a patient with a laboratory diagnosis of factor X deficiency (FXD), a rare bleeding disorder.


The gene target for this test is:

Gene name (transcript): F10 (GRCh 37 [hg19] NM_000504)

Chromosomal location: 13q34

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

The clinical workup for factor X deficiency (F10D) begins with special coagulation testing for factor X. See F_10 / Coagulation Factor X Activity Assay, Plasma.


Genetic testing for F10D is indicated if:

-Factor X clotting activity is reduced (less than 80% of normal)

-Acquired causes of factor X deficiency have been excluded (eg, liver disease, warfarin therapy, vitamin K deficiency, systemic amyloidosis, and inhibitors)
