First test to detect recently discovered autoimmune disease associated with testicular cancer

June 16, 2021

Mayo Clinic Laboratories has launched a first-of-its-kind test to detect an autoimmune disease called
testicular cancer-associated paraneoplastic encephalitis. The test, available nationally and internationally, detects the Kelch-like protein 11 antibody, or KLHL11, and is a result of the breakthrough study from 2019 that discovered the disease. This test has already provided patients, such as Steven Wopperer of Temecula, California, a diagnosis after he struggled for three years to find an answer to his vision and balance problems.

The disorder causes the immune system to attack the brain, causing severe neurologic symptoms. That's what happened to Gregor Heinrich of Boca Raton, Florida.
