Background/aims

Kisspeptin (KISS1)/GPR54 (KISSR) signaling complex and neurokinin B (NKB)/NKB receptor (TACR3) signaling have been proposed as an integral part of the network coordinating GnRH release. GPR54 (KISS1R) and TACR3 gene mutations have been described in cases of idiopathic hypogonadotrophic hypogonadism, while limited data exist on gain-of-function mutation in GPR54 (KISS1R) gene causing idiopathic central precocious puberty (ICPP). No data on TACR3 mutations in ICPP have been described so far. The aim of this study was to elucidate the possible impact of GPR54 (KISS1R) and TACR3 mutations in ICPP.

Methods

PCR-amplified genomic DNA of 38 girls with ICPP was analyzed for GPR54 and TACR3 gene mutations.

Results

No GPR54 or TACR3 mutations were found. The A/G coding sequence single nucleotide polymorphism (SNP) on the GPR54 gene (dbSNP ID: rs10407968) was found in 2 patients with ICPP.

Conclusion

Our data indicate that GPR54 and TACR3 gene mutations are not a frequent cause of ICPP. The identified A/G synonymous SNP (dbSNP ID: rs10407968) located in exon 1 of the gene is not likely to have a pathogenic role in exon splicing and therefore in the premature initiation of puberty."xsd:string
