Test ID: CYPPS    
21-Hydroxylase Gene (CYP21A2), Full Gene Analysis

NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.

Conditional

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

Carrier screening and diagnosis of 21-hydroxylase deficient congenital adrenal hyperplasia (CAH) as follow-up to positive CAH newborn screens and/or measurement of basal and adrenocorticotropic hormone- 1-24 stimulated 17-hydroxyprogesterone, androstenedione, and other adrenal steroid levels

 

May be used to identify CYP21A2 mutations in individuals with a suspected diagnosis of 21-hydroxylase deficient CAH when a common mutation panel is negative or only identifies 1 mutation

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

This test includes Sanger gene sequencing and multiplex ligation-dependent probe amplification to evaluate the CYP21A2 gene on whole blood specimens for carrier screening and diagnosis of 21-hydroxylase deficient congenital adrenal hyperplasia (CAH).

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.
