Story summary
- A new study links maternal gene variants to chromosomal abnormalities that cause pregnancy loss.
- Researchers analyzed data from over 139,000 in vitro fertilization embryos and found associations between maternal variants and aneuploid embryos.
- Key genes identified include SMC1B and C14orf39, involved in chromosome stability and crossover recombination.
- The findings are not yet applicable to patient care, but recombination errors may raise aneuploidy risk and infertility.
