WebCauses / Inheritance What causes SBMA? The genetic flaw in X-chromosome spinal-bulbar muscular atrophy (SBMA) is an expanded section of DNA — called a trinucleotide repeat — in a gene that carries instructions for a protein known as the androgen receptor. The normal function of the androgen receptor is to help cells process androgens (male hormones). WebDistal hereditary motor neuropathy, type V is a progressive disorder that affects nerve cells in the spinal cord. It results in muscle weakness and affects movement of the hands and feet. Symptoms of distal hereditary motor neuropathy, type V usually begin during adolescence, but onset varies from infancy to the mid-thirties. hawaiian carved candles
