If we think cardiac muscle can work independently . Peirone A, Bruno E, Rossi N, Alday LE. While autosomal dominant inheritance is the primary method of transmission, penetrance is quite variable in patients. Naxos disease is a recessive association of arrhythmogenic right ventricular cardiomyopathy (ARVC) with wooly hair and palmoplantar keratoderma or similar skin disorder. The aim of this article is to present arrhythmogenic right ventricular cardiomyopathy (ARVC) and the associated cardiocutaneous syndromes, Naxos and Carvajal, with extension on the left ventricle . Mutations in genes encoding the cell adhesion proteins like plakoglobin and desmoplakin were related with these syndromes. A recessive mutation of DSP has been reported and associated with Carvajal syndrome, another cardiocutaneous disease. At the same time, experienced dermatologists will find this book a valuable reference work for differential diagnosis. Conceived as a guide for practitioners in their work in dermatology, this book is unique in its approach. Carvajal Syndrome shares common clinical features with another autosomal recessive cardiocutaneous disorder known as Naxos Disease, except that the former has prominent left ventricular involvement with earlier involvement in childhood [2, 4, 5]. 2020 Sep 10;21(18):6615. doi: 10.3390/ijms21186615. desmosomal genes and rare recessive forms (e.g. Carvajal syndrome. 13, 14, 15, 22 In contrast, the phenotype of heterozygote carriers remains uncertain.

Naxos disease, first described by Dr. Nikos Protonotarios and colleagues on the island of Naxos, Greece, is a special form of arrhythmogenic right ventricular dysplasia (ARVD). A variety of Naxos disease presenting at a younger age with more pronounced left ventricular involvement has been described in families from India and Ecuador (Carvajal syndrome). condition inherited in an autosomal recessive pattern due to a defect in desmoplakin gene.
