It is worth noting that the anti‐TSNARE1 IgG assay has the highest sensitivity (true positive) of 15.7% (19.3% in males) against a specificity (true negative) of 95.2%, suggesting that anti‐TSNARE1 IgG may be indicative of a subgroup of schizophrenia. This evidence concerns the gene TSNARE1 and schizophrenia.
