SUMMARY

The increase in maternal age significantly elevates the risk of Down Syndrome in offspring due to various molecular mechanisms, including chromosomal abnormalities during meiosis. Specifically, advanced maternal age is associated with age-related decline in oocyte quality and increased likelihood of nondisjunction events. Research indicates that the risk of Down Syndrome rises sharply after the age of 35, as evidenced by studies such as those found in the article from the National Center for Biotechnology Information (NCBI).

PREREQUISITES
  • Understanding of meiosis and chromosomal segregation
  • Knowledge of oocyte development and quality
  • Familiarity with genetic disorders, specifically Down Syndrome
  • Basic grasp of maternal age-related reproductive biology
NEXT STEPS
  • Research the role of oocyte quality in maternal age and chromosomal abnormalities
  • Study the mechanisms of nondisjunction in meiosis
  • Explore genetic counseling practices for advanced maternal age
  • Investigate current research articles on maternal age and Down Syndrome risk
USEFUL FOR

Geneticists, reproductive health specialists, healthcare professionals, and researchers interested in maternal health and genetic disorders.

Why does increase in age of the mother increases the chance of having an offspring with Down Syndrome?

I want to know the molecular basis of this observation. I'll be grateful if somebody could recommend an authentic source in this regard.
