Incidence of hyperbilirubinemia as a function of presence of the G-6-PD Mediterranean mutation and the UDPGT1 genotype

G-6-PD Mediterranean	Incidence of UDPGT1 genotype
	6/6	6/7	7/7	Total
Present (deficient)	6/62 (9.7%)	18/57 (31.6%)	6/12 (50%)	30/131 (22.9%)
Absent (normal)	10/101 (9.9%)	7/105 (6.7%)	5/34 (14.7%)	22/240 (9.2%)
Significance	NS	P < 0.0001	P = 0.02	P = 0.0005

6/6, Homozygous normal UDPGT1 genotype; 6/7, heterozygous variant UDPGT1 genotype; 7/7, homozygous UDPGT1 genotype.
