Recently, another familial DCM, associated with germline KIT A533D (an autosomal dominant gain-of-function germline KIT variant: c.1598C > A, p.Ala533Asp), has been reported in a six-month-old boy with bullous lesions and fever and in his mother, who had a history of blistering in childhood and carried the same mutation [52]. The gene discussed is KIT; the disease is familial dilated cardiomyopathy.
