Dataset of allele, genotype and haplotype frequencies of four LIN28B gene polymorphisms analyzed for association with age at menarche in Russian women.

In this paper, we present the allele, genotype and haplotype frequencies of 4 single nucleotide polymorphisms (SNPs) in LIN28B gene (rs4946651, rs7759938, rs314280, rs314276) in a sample of Russian women. These SNPs had been previously identified to be associated with age at menarche in genome-wide association studies (GWAS). The information about age at menarche was obtained using the questionnaire. The frequencies of alleles, genotypes and haplotypes of four SNPs were classified in 3 groups: the whole sample, individuals with the early age at menarche (<12 years), and those with the average age at menarche (12-14 years).
