Despite its testis-restricted expression profile, the previously established OMIM phenotype associated with ACTRT1 gene was Bazex–Dupré–Christol syndrome (BDCS; OMIM: 301845), an X-linked dominant genodermatosis characterized by follicular atrophoderma, congenital hypotrichosis, and early-onset multiple basal cell carcinomas [29,30]. The gene discussed is ACTRT1; the disease is nevoid basal cell carcinoma syndrome.
