General Discussion

Kennedy Disease is a rare, slowly progressive muscular disorder that affects males only and is inherited as an X-linked genetic trait. Uncontrollable twitching (fasciculations) followed by weakness and wasting of the muscles becomes apparent sometime after the age of fifteen. The muscles of the face, lips, tongue, mouth, throat, vocal chords, trunk and limbs may be affected. Very large calves may also be found in some patients with this disorder. Kennedy disease is caused by a mutation in the androgen receptor (AR) gene. Androgen insensitivity leads to abnormal swelling of the breasts (gynecomastia), small testes and infertility.
