ABSTRACT

Objective: This study aimed to assess the relation of locus 1p13 rs646776 (T/C) polymorphism with preeclampsia in Egyptian women.

Methods: The study included 100 healthy pregnant female subjects and 100 preeclampsia patients. The genotypes of the polymorphisms were assessed. Endothelin-1 level was determined in plasma.

Results: The major T allele of the 1p13.3 genomic region rs646776 polymorphism had a higher frequency in preeclampsia patients. Carriers of C allele had significantly lower endothelin-1 levels, lower systolic and diastolic blood pressure, decreased proteinuria, and increased HDL-C in the patients.

Conclusion: The rare C allele of rs646776 polymorphism in chromosomal locus 1p13.3 is associated with decreased risk of preeclampsia.
