ABSTRACT
Spinal and bulbar muscular atrophy is an X-linked neuromuscular disease caused by a trinucleotide CAG repeat expansion in the androgen receptor gene; it is clinically characterized by adult-onset, slowly progressive weakness and atrophy mainly affecting proximal limb and bulbar muscles. Charcot-Marie-Tooth disease type 1A is an autosomal dominant polyneuropathy due to peripheral myelin protein 22 gene duplication and characterized by slowly progressive distal limb muscle weakness, atrophy and sensory loss with foot deformities. Here we report the co-occurrence of both neuromuscular genetic diseases in the same male patient. Difficulties in climbing stairs and jaw weakness were presenting symptoms consistent with SBMA. However, predominant distal weakness and bilateral pes cavus were rather suggestive of a hereditary polyneuropathy. The combination of two diseases, even if extremely rare, should be considered in the presence of atypical symptoms; in the case of genetic diseases this event may have important implications on family members' counseling.
