After adjusting for the number of women tested, an excess of women persisted (adjusted F:M 3.6:1). Female predominance for AQP4-IgG was more striking in adults (absolute F:M, 8.4:1; adjusted, 3.5:1) than in pediatric patients (absolute F:M, 4.3:1; adjusted, 2.9:1; p<0.001). These findings were concordant in a subgroup of Mayo Clinic AQP4-seropositive patients whose diagnoses were known. The proportion of AQP4 seropositive individuals (detection rate), defined by decade of age, increased exponentially in women after age 50 (p<0.001).Conclusions: AQP4-seropositivity occurs predominantly in women, particularly in individuals >18 years of age. One in six seropositive patients are in the extremes of age. In women, but not men, AQP4-IgG seropositivity increases exponentially beyond age 50.Supported by: Guthy-Jackson Charitable Foundation and NIH (NS065829).Disclosure: Dr. Quek has nothing to disclose.
