| Summary: | Introduction: Jaundice is a common condition during the
neonatal period. Prolonged jaundice occurs in a large number
of breastfed infants, considering the impact of genetic factors
on the incidence of jaundice.
Aim: To determine the association between prolonged jaundice
and TATA box dinucleotide repeats in Gilbert’s Syndrome (GS).
Materials and Methods: In this case-control study, the case
group consisted of 51 neonates with jaundice, aged more than
two weeks with indirect bilirubin level higher than 10 mg/dl. Acute
diseases, mother’s use of phenobarbital and other medications
were the exclusion criteria. The control group consisted of 54
newborns without jaundice. The two groups were matched in
terms of age and sex. TATA box polymorphisms in the promoter
region of UGT1A1 gene were evaluated using Polymerase Chain
Reaction (PCR) in order to determine TATA box dinucleotide
repeats.
Results: Overall, 64.7% and 50% of subjects in the case and
control groups were male, respectively (p=0.168). The mean age
of neonates in the case and control groups was 20.1±7.1days
and 18.8±4.1 days, respectively. The distribution of Gilbert
genome was not significantly different between the two groups.
In the case group, 13.7% of the subjects were homozygous,
37.3% were heterozygous and 49% were normal. In the control
group, 7.4% of the participants were homozygous, 35.2% were
heterozygous and 57.4% were normal.
Conclusion: The results of this study showed an association
between TATA box polymorphism and prolonged jaundice in
neonates which revealed that TATA box polymorphism is an
important risk to increase and extend icterus. |
