INDIVIDUAL TEST 737
SOX1 Antibodies (IgG)
Indication
Suspicion of paraneoplastic syndrome and ambiguous forms of neuropathy.
Method
Immunoblot.
Result
Serum: The result is reported as negative, borderline or positive with a value (blot intensity).
CSF: The result is reported as negative, borderline or positive
Interpretation
Antibodies against SOX1 (or anti-glial nuclear antibody, AGNA) are unusual but have been reported to occur in paraneoplastic neuropathy, Lambert-Eaton syndrome and in unclear forms of neuropathy and ataxia. SOX1 antibodies are often associated with antibodies against VGCC, Hu, CV2 / CRMP5 or amphiphysin. The most common cancer form associated with SOX1 is small cell lung cancer, but other lung cancer forms have also been reported.
Antibodies against SOX1 are graded as Higher-risk antibodies with a frequency of >90% of underlying cancer and a positive result yield 3 points PNS score, according to Updated Diagnostic Criteria for Paraneoplastic Neurologic Syndromes.

ENSKILD ANALYS 737
SOX1-antikroppar (IgG)
Indikation
Misstanke om paraneoplastiska syndrom och oklara former av neuropati.
Metod
Immunoblot.
Resultat
Serum: Resultatet anges som negativt, gränsvärde eller positivt med värde (blot intensitet).
Likvor: Resultatet anges som negativt, gränsvärde eller positivt.
Tolkning
Antikroppar mot SOX1 (anti-glial-nuclear-antibody, AGNA) är ovanliga men har rapporterats förekomma vid paraneoplastisk neuropati, Lambert-Eaton Syndrom och vid oklara former av neuropati och ataxi. SOX1 antikroppar kan förekomma tillsammans med autoantikroppar mot VGCC, Hu, CV2/CRMP5 eller amphiphysin. Den vanligaste cancerformen som är associerad med SOX1 är småcellig lungcancer, men även andra lungcancerformer har rapporterats.
Antikropparna riktade mot SOX1 bedöms vara Higher-risk antibodies med en förekomst på >90 % för en underliggande cancer och positivitet ger 3 poäng i PNS score enligt Updated Diagnostic Criteria for Paraneoplastic Neurologic Syndromes.
