Table 3. Distribution of the CPS1 genotypes for the polymorphism at position 1405 in healthy term infants.

	CC genotype	CA genotype	AA genotype
Las Palmas de Gran Canaria (Spain), n = 31	19 (61.3)	7 (22.6)	5 (16.1)
Mantova (Italy), n = 40	22 (55.0)	15 (37.5)	3 (7.5)
Maastricht (the Netherlands, ref. 24), n = 25	11 (44.0)	12 (48.0)	2 (8.0)
Total study group, n = 96	52 (54.2)	34 (35.4)	10 (10.4)

Results are expressed as absolute numbers of patients (percentage). CC denotes homozygosity for the C-encoded Thr1405 variant, AA homozygosity for the A-encoded Asn1405 variant, and AC heterozygosity for this polymorphism.
