title: Frequency and origin of G-6-PD deficiency among icteric newborns in the metropolitan area of Monterrey, Nuevo León, Mexico.
abstract: 829 icteric newborn males were studied in order to have more information about the frequency of the G-6-PD deficiency and its origin in the population of the Monterrey Metropolitan area (MMA), in northeastern Mexico. For each subject information about the maternal grandparents' birthplace (states of Mexico) was gathered. The newborns were grouped into five geographic areas. It was found that the frequency of G-6-PD deficiency is higher in icterics than in normal newborns. The grandparents of the deficient newborns with variant B belonged to the northeastern states of Mexico where more European genetic contribution was present whereas most of the grandparents of the A- deficient newborns were from the gulf coast states, where the genetic contribution was African.
