Title: Cyclic Seasonal Variation of G-6-PD Deficiency in Newborn Infants from Sardinia

Contents: Glucose-6-Phosphate Dehydrogenase has been studied in 5267 consecutive newborn infants from Sardinian population during a four years period. The proportion of G-6-PD deficient female infants is much higher in those conceived in the winter-spring than among those conceived in summer-autumn, resulting in a lower sex ratio among G-6-PD deficient infants conceived in winter-spring as compared to G-6-PD deficient infants conceived in the summer-autumn. The overall frequency of the gene for G-6-PD deficiency is much lower in infants conceived in the summer period than in infants conceived in the other seasons. A greater reproductive efficiency of G-6-PD deficient males in the winter-spring season and/or some effect at post zygotic level favouring the survival of heterozygous G-6-PD deficient females conceived in the winter-spring period could contribute to the pattern described. Fresh vegetables containing oxidative substances are more abundant in the spring time. These substances may interact with seasonal reproductive cycles influencing reproduction efficiency of G-6-PD deficient males and/or the relative survival rate of heterozygous female embryos.
