Questions: Can the serum levels of kisspeptin and DLK1 be potential biomarkers for monitoring the treatments for central precocious puberty (CPP)?
Findings: There were no significant differences in the baseline serum kisspeptin and DLK1 levels in CPP girls compared to girls with premature thelarche (PT). After 6 months of GnRH analogue treatment in CPP girls, median serum kisspeptin levels decreased, while median serum DLK1 levels increased compared to baseline.
Meanings: Serum levels of kisspeptin and DLK1 may serve as novel biomarkers for monitoring the efficacy of treatments for CPP.

Genetic factors in precocious puberty
Young Suk Shim, Hae Sang Lee, Jin Soon Hwang
Clin Exp Pediatr. 2022;65(4):172-181.   Published online October 18, 2021
· Mutations in the kisspeptin (KISS1), kisspeptin receptor (KISS1R), makorin ring finger protein 3 (MKRN3), and delta-like homolog 1 (DLK1) genes are associated with idiopathic central precocious puberty (ICPP).
· A few genes related to pubertal onset have been implicated in ICPP.
· Epigenetic factors such as DNA methylation, histone posttranslational modifications, and noncoding ribonucleic acids may be related to ICPP
