Study of rs7759938 , rs314280 , and rs314276 Polymorphisms of LIN28B in Relation to Age at Menarche in Girls of Greek Descent.

There was no association between age at menarche and any of the polymorphism genotypes/alleles or between genotypes/alleles and birth weight, gestational week, mode of delivery, and maternal age at menarche. Future large sample studies are warranted to confirm these results.
