Association study of LIN28B in girls with precocious puberty
-
Yen-Chun Chen
Abstract
Background:
Central precocious puberty (CPP), predominant in girls, is defined by early development of secondary sexual characteristics driven by the early secretion of hypothalamic gonadotropin releasing hormone (GnRH) and subsequent gonadotropin. Recent studies have shown variation in the LIN28B gene is associated with timing of puberty, but only a few have show it to be associated with CPP.
Methods:
This study attempted to investigate the relation between single-nucleotide polymorphisms (SNPs) in LIN28B and girls with precocious puberty. Genotype and alleles frequencies of selected SNPs were compared between 116 girls with CPP and 102 controls.
Results:
We found genotype frequencies in rs314276 and rs221634 were significantly correlated with girls with CPP; while the C allele frequency in rs314276 showed the dominant trait. Standard deviation score (SDS) of weight and body mass index (BMI) were higher in CC homozygotes of rs314276 in girls with CPP.
Conclusions:
Our results demonstrate that the genotype of rs314276 in LIN28B is associated with girls with CPP, carrying dominant trait in the C allele.
