چکیده مقاله:

Introduction: Restrictive cardiomyopathy accounts for 2.5-5% of all types of cardiomyopathy. It has a heterogeneous etiology; here, we report a case of RCM due to a novel variant in TNNI3 gene.Materials & Methods: A 2 years-old female referred to Rajaei Hospital. Clinical evaluations, echocardiogram and cardiac MRI were performed. Coding regions of TNNI3 gene were amplified and sequenced. In silico analysis was done using mutationtaster and CADD software tools.Results: Moderate RV dysfunction and LVEF 35% leading to HT (heart transplantation) were noticed in the patient. She had a sister died cause of SCD when she was 1 year old. We found a homozygous novel variant (c.406C> T) in patient. Therefore we examined this variant for other members of her family and confirmed in her parent and brother but not founded in her sister Conclusion & discussion: It seems that autosomal recessive type of RCM may have a high frequency in Iran TNNI3 gene may have a major role and it is recommended to check in more RCM patients
