Test ID: SDHDD    
Succinate Dehydrogenase (SDH) Gene, Deletion Detection

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


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

Aiding in the diagnosis of hereditary paraganglioma-pheochromocytoma syndrome by detection of a large (single- or multi-exon) deletion of the SDHB, SDHC, or SDHD genes when sequence analysis of these genes detects no mutations


Diagnosis of hereditary paraganglioma-pheochromocytoma syndrome, when a large familial deletion of SDHB, SDHC, or SDHD has been previously identified (involving one exon or multiple exons)


Screening presymptomatic members of hereditary paraganglioma-pheochromocytoma syndrome families, when a large familial deletion of SDHB, SDHC, or SDHD has been previously identified (involving one exon or multiple exons)

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

This test is intended for patients for whom a large SDHB, SDHC, or SDHD gene deletion has been previously identified in the family, or for patients whom have previously undergone sequence analysis of SDHB, SDHC, and SDHD with negative results. For additional guidance, contact the laboratory genetic counselor at 800-533-1710.


If performing testing for a known familial large deletion, documentation of the specific familial deletion must be provided with the specimen in order to perform this test.

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