Intra-Family Marriages: Are Genetic Risks to Babies Being Overlooked?

• Intra-family marriages, though culturally familiar, carry higher risks of congenital anomalies in babies due to shared genetic factors.
• Dr. Nirmala Chandrashekar highlights that close relatives share similar genetic material, increasing the chance of both partners carrying the same recessive faulty gene.
• A NIH study shows congenital anomaly risk rises from 0.7% in non-related marriages to 3.8% in consanguineous unions.
• Closer biological relationships, like first cousins, significantly increase the chances of genetic disorders, developmental delays, and physical anomalies.
• Pre-marital genetic counseling, carrier testing, and prenatal screening can help mitigate risks and inform families.
