Test ID: VHLSP    
Von Hippel-Lindau (VHL) Gene, Full Gene Analysis

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

89083

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

Diagnosis of suspected von Hippel-Lindau (VHL) disease

 

Screening presymptomatic members of VHL families

 

Diagnosis of hereditary erythrocytosis

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.

Test IDReporting NameAvailable SeparatelyAlways Performed

VHLGQVHL Gene SequencingNoYes

Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)

VHDDVHL Deletion DetectionYes, (order VHLD)No

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

If reason for referral is diagnosis of von Hippel-Lindau (VHL) syndrome or it is not known both VHL full gene analysis (amplification) and VHL gene sequencing will be performed.

 

If VHL gene sequencing does not identify a mutation, then VHL deletion detection will be performed at an additional charge.

 

If reason for referral is erythrocytosis or polycythemia, order HEMP / Hereditary Erythrocytosis Mutations. If the mutation panel is negative, then VHL full gene analysis will be performed. VHL deletion detection testing will not be routinely performed as large gene deletions in the VHL gene have not been described in the literature in relation to erythrocytosis or polycythemia.
