What do Onconeural antigens do?
Certain onconeural antigens can serve as paraneoplastic antigens under conditions which have yet to be defined, implying that the paraneoplastic function is not inherent to the antigen. The potential of onconeural antigens in cancer diagnostics and treatment strategies is discussed.
What are paraneoplastic antibodies?
Description. A family of autoantibodies recognising antigens in the brain which are associated with a variety of neurological manifestations occurring as a result of malignancy, usually ovarian or small cell carcinoma of the lung.
What is an SOX1 antibody?

What is Amphiphysin antibody?
Amphiphysin antibody is present in about 5 percent of patients with stiff-person syndrome and is found variably in other causes of paraneoplastic neurological syndrome (PNS). Amphiphysin antibody is mainly associated with small-cell lung cancer and breast tumors.

Stiff-person syndrome (SPS) is a rare neurological disorder with features of an autoimmune disease. SPS is characterized by fluctuating muscle rigidity in the trunk and limbs and a heightened sensitivity to stimuli such as noise, touch, and emotional distress, which can set off muscle spasms.
What is a paraneoplastic autoantibody evaluation?
Paraneoplastic autoimmune neurological disorders reflect a patient’s humoral and cellular immune responses to cancer. The cancer may be new or recurrent, is usually limited in metastatic volume, and is often occult by standard imaging procedures.
What is Samson syndrome symptoms?
They determined that Samson’s behavior, as described in Judges 13 to 16, met the diagnostic criteria for deceitfulness, a failure to conform to social norms and defiance of the law, impulsivity, irritability and aggressiveness, flagrant disregard for the safety of self and others, and a lack of remorse for his actions.

What is the average life expectancy of someone with Stiff Person Syndrome?
What is the life expectancy of a patient with stiff person syndrome? The life expectancy for people with SPS ranges from 6 to 28 years from the onset of the condition.
