Developmental Lactase Deficiency: This form of lactase deficiency occurs in premature infants. Lactase enzyme activity usually develops late in pregnancy so a preterm infant will not yet have developed this enzyme function. The greater the degree of prematurity, the greater the reduction in lactase activity.
