ADIPOQ and Pregnancy: What Your rs2241766 Genotype May Mean for Fetal Heart Health

Pregnancy demands a careful balance of metabolism and inflammation to support healthy fetal growth. The ADIPOQ gene makes adiponectin, a hormone that helps regulate both metabolic and inflammatory processes. Variations in ADIPOQ can change how the body responds to diet and environmental stressors, which could influence fetal development, including the developing heart.

This article explains how the rs2241766 variant in ADIPOQ may interact with maternal diet during pregnancy and offers practical, evidence-informed strategies to support a healthier pregnancy. PlexusDx does not provide medical advice. This information is educational only. Always discuss genetics and pregnancy planning with your healthcare provider before making changes to diet, supplements, or care plans.

Why cooking method and diet matter

High-heat cooking methods like frying, smoking, and direct BBQ grilling can produce compounds that increase inflammation and oxidative stress. In pregnancy, excess inflammation and oxidative stress may interfere with normal fetal development. Adiponectin helps control inflammation and metabolic balance. If ADIPOQ function is altered by a genetic variant, the body may be less able to buffer harmful effects from certain dietary exposures.

Regardless of genotype, emphasizing whole foods and gentle cooking supports maternal health and fetal development. The recommendations below are practical steps to reduce exposure to harmful compounds and to promote nutrients that support fetal heart development.

Diet and cooking recommendations

  • Limit fried, smoked, and high-heat BBQ foods. Reduce intake of charred or heavily browned meats and fried snacks.
  • Prefer gentle cooking methods such as steaming, boiling, poaching, and baking at moderate temperatures.
  • Increase antioxidant-rich foods: a variety of fruits and colorful vegetables, legumes, nuts, and whole grains.
  • Choose lean proteins and prepare them without charring. When grilling, use lower direct heat and avoid prolonged charring.
  • Include sources of omega-3 fats such as fatty fish low in mercury, walnuts, chia seeds, or algae-based supplements if advised by your provider.
  • Stay hydrated and maintain balanced meals to support stable blood sugar and metabolic health.

Supplement and nutrient considerations

  • Take a comprehensive prenatal vitamin containing folate (or methylfolate if recommended), vitamin B12, and vitamin C.
  • Include choline, important for brain and heart development; many prenatal vitamins include choline or it can be taken separately per provider guidance.
  • Consider omega-3 fatty acids (DHA/EPA) if not regularly consuming low-mercury, fatty fish—talk with your provider for dosing.
  • Discuss personalized needs with your healthcare provider before starting any new supplements.

Lifestyle, planning, and prenatal care

  • Plan early: preconception health and nutrition optimization give the best chance for healthy fetal development.
  • Attend regular prenatal visits so your care team can monitor fetal growth, screen for risks, and tailor advice.
  • Manage stress, sleep, and physical activity within pregnancy-appropriate guidelines to support metabolic and inflammatory balance.
  • Avoid tobacco, excessive alcohol, and other exposures known to increase inflammation or harm fetal development.

Genetic interpretations for ADIPOQ rs2241766

Two effect alleles (GG) — increased sensitivity to high-heat cooked foods

If you have the GG genotype for rs2241766, you carry two copies of the effect allele. This genotype has been associated with a higher risk that maternal diets high in fried, smoked, or BBQ foods may contribute to congenital heart disease in offspring. Your ADIPOQ variant may alter adiponectin signaling, which can influence how your body handles inflammation and metabolic stress from high-heat–generated compounds.

Practical steps:

  • Strongly limit fried, smoked, and charred BBQ foods during pregnancy and in the preconception period.
  • Use steaming, boiling, poaching, or baking at moderate temperatures instead of frying or direct high-heat grilling.
  • Prioritize antioxidant-rich foods daily: a wide variety of fruits, vegetables, and whole grains.
  • Take a comprehensive prenatal vitamin that includes folate, choline, vitamin B12, omega-3 fatty acids, and vitamin C as advised by your provider.
  • Begin these dietary adjustments prior to conception if possible and maintain regular prenatal care for monitoring and support.
One effect allele (GT) — moderate sensitivity to high-heat cooked foods

If you have the GT genotype for rs2241766, you carry one copy of the effect allele. This variant may moderately influence the interaction between maternal diet and fetal heart development. Frequent consumption of fried, smoked, or BBQ foods during pregnancy may raise risk compared to diets that minimize these foods.

Practical steps:

  • Limit intake of fried, smoked, and charred BBQ foods during pregnancy and ideally while planning pregnancy.
  • Choose gentler cooking methods such as steaming, baking, or poaching to reduce formation of harmful compounds.
  • Emphasize antioxidant-rich foods: colorful fruits, vegetables, legumes, and whole grains.
  • Use a prenatal supplement including folate, choline, B12, omega-3s, and vitamin C under the guidance of your healthcare provider.
  • Engage in early prenatal care and discuss dietary strategies with your care team.
No effect alleles (TT) — typical adiponectin function

If you have the TT genotype for rs2241766, you carry two copies of the non-effect allele. Your genotype is associated with typical adiponectin function and standard metabolic and inflammatory regulation during pregnancy. Unlike carriers of the G allele, this variant does not appear to increase susceptibility to the interaction between high-heat cooking and congenital heart defect risk.

Practical steps:

  • Although your genetic risk for this specific interaction is lower, follow general pregnancy nutrition and cooking guidance to support fetal development.
  • Maintain a diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats.
  • Take a comprehensive prenatal vitamin with folate, choline, B12, omega-3s, and vitamin C as recommended by your provider.
  • Attend routine prenatal care and discuss any concerns with your healthcare team.
