Abstract
Over a 12-year period (1983 to 1994), 11 cases of classical galactosaemia were identified in the Saudi Aramco Medical Services Organization (SAMSO). This yields an incidence of 12 cases per 100,000 live births in the Easter Province of Saudi Arabia. A higher proportion of infants presented with infections compared to reports in the literature. Screening for galactosaemia is highly recommended in this high-risk population.
