Abstract

Background: The aim of the study was to analyze spectrum of manifestation and treatment response in large family with rhythm disturbances caused by p.delKPQ1505-1507 mutation in SCN5A gene. Patients and methods: We had under our observation 18 members of large Iranian family with various combination of inherited arrhythmic syndromes. Careful cardiological examination, genetic councelling and venous blood sampling for molecular genetic study were performed for family members. Mutation screening in SCN5A gene was performed using bidirectional Sanger sequencing. Results: Here by we show the observation of Iranian family with known mutation p.delKPQ 1505-1507 in SCN5A gene, who display not only LQ–TS phenotype but also some of the carriers of this mutation have had LQ–TS and Brugada syndrome (combine phenotype), interestingly. Conclusion: The overlapping phenotype associated with high risk of sudden cardiac death may require complex approaches to antiarrhythmic therapy, surgical treatment and prevention of sudden cardiac death in the family.
