Defective folate metabolism causes germline epigenetic instability and distinguishes Hira as a phenotype inheritance biomarker

Abstract

Abnormal folate metabolism in mice results in transgenerational epigenetic inheritance of congenital malformations. Here, the authors provide evidence that defective folate metabolism causes germline epigenetic instability and observe multigenerational misexpression of Hira in embryos, implicating Hira transcript levels as a biomarker of maternal phenotypic inheritance.
