From a longitudinal cohort study of children (N = 206, 5–14 years) who were resident in a malaria-endemic region of PNG [25], only a minority had antibodies that promoted C1q-fixation to CSP (positivity 40%), weakly correlating with anti-CSP IgG (rho = 0.280, 95% CI 0.140 to 0.409; p < 0.001). This evidence concerns the gene DNAJC5 and malaria.
