Introduction
We simultaneously sequence 12 genes known to cause inherited long QT syndrome. We provide a comprehensive scientific interpretation of variants found and issue a report summarising our findings.
Referral information
For individuals with clinical features and investigations consistent with published criteria for LQT (Circulation 1993;88:782-784.). On identification of a pathogenic change in an index case presymptomatic testing of relatives can be offered. Referrals for testing are only accepted from a Consultant Cardiologist or a Consultant Clinical Geneticist (please contact the Clinical Genetics department for specific information). Referrals should be accompanied by a clinical diagnosis and details of family history. Referrals should also be accompanied by a completed standard referral form available in the Referral Forms section. For optimal results please send a fresh EDTA blood sample (1-4ml) or a minimum of 5µg of extracted DNA. For a full list of genes included in the assay please contact the laboratory.
