ABSTRACT
Spinal and bulbar muscular atrophy (SBMA) is a rare X-linked recessive neurodegenerative disorder caused by the excessive expansion of cytosine-adenine-guanine repeat sequences in the androgen receptor gene encoded on the Xq11-12 chromosome. SBMA primarily affects adult males and is characterized by weakness and atrophy of the proximal limb muscles, often involving the bulbar muscles. In addition to neuromuscular deficits, nonneuronal symptoms such as hypertension, hyperlipidemia, and liver dysfunction are often observed in patients with SBMA. Previous studies have suggested that SBMA patients have been diagnosed with hypertrophic cardiomyopathy (HCM), while gene detection is lacked. Moreover, according to current reports, SBMA patients can carry Brugada syndrome or HCM respectively, while three kinds of diseases have not been reported to exist in the same patient. Here, we report the first case of a male diagnosed with SBMA combined with HCM and two types of Brugada-pattern electrocardiographic changes, with a heterozygous missense mutation in the TTN gene.
