TMEM43 (Transmembrane protein 43) variants and mutations

TMEM43 (also known as Transmembrane protein 43) is a human protein-coding gene encoding a transmembrane protein 43 protein. A multi-pass membrane protein that helps organize protein complexes at the inner nuclear membrane and retain emerin. It also participates in innate-immune signaling and contributes to electrical coupling in the inner ear, with variants linked to cardiomyopathy and auditory neuropathy. This analysis covers 758 TMEM43 variants and mutations. Of these, 93% have computational variant effect predictions. Disease context includes arrhythmogenic right ventricular dysplasia 5, Emery-Dreifuss muscular dystrophy 7, autosomal dominant, and Arrhythmogenic right ventricular dysplasia. Example TMEM43 variants include M1I, M1K, and M1V.
