Test ID: FAPMS    
Familial Adenomatous Polyposis (FAP) Mutation Screen

Secondary ID A test code used for billing and in test definitions created prior to November 2011

82582

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

Confirmation of familial adenomatous polyposis (FAP) diagnosis for patients with clinical features

 

This test should be ordered only for individuals with symptoms suggestive of FAP. Asymptomatic patients with a family history of FAP should not be tested until a mutation has been identified in an affected family member.

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

APC gene sequence analysis for exons 1-14 and PTT for exon 15. Changes identified in exon 15 via PTT are verified by DNA sequencing. Gene dosage analysis by multiplex ligation probe amplification (MLPA) is used to investigate for the presence of large deletions and duplications encompassing the coding regions as well as promoter 1A and 1B of the APC gene.

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
