Clinical System Name

Telomere Length, Full Panel


Requests for telomere length measurements are typically from physicians curious to know whether the clinical problems of their patients could be related to cellular defects resulting from extremely short telomeres. Flow-FISH measurements have been shown to be valuable as a screening test for inherited telomere maintenance deficiencies resulting from mutations in dyskerin, telomerase RNA (hTERC), telomerase reverse transcriptase (hTERT) and other genes.
