The prevalence of the Leiden mutation was tested in 50 mothers of premature infants and in 56 mothers of intrauterine-growth-retarded neonates. The prevalence of the Leiden mutation was 7.2% in the mothers of growth-retarded neonates and 18% in the group of mothers of premature infants, the latter being significantly higher than the 6.3% prevalence of this mutation in healthy Hungarian subjects (p < 0.01). In spite of the relatively small number of mothers examined, the unexpected finding may call attention to a hitherto unknown relationship.
