How a mother's vitamin A during pregnancy affects a baby's risk and severity of cleft lip and palate

Impact of maternal dietary vitamin A on risk and severity of cleft lip/palate in genetically sensitized embryos

NIH-funded research University of Missouri Kansas City · NIH-11321214

Researchers are looking at whether a mother's vitamin A intake during pregnancy changes the chance and severity of cleft lip or palate in babies who are genetically prone to it.

What this research studies

This work uses established mouse models that carry genes linked to cleft lip and/or palate to see how maternal vitamin A levels influence whether a cleft occurs and how severe it is. The team will alter vitamin A in the mother’s diet during pregnancy and examine embryos for cleft formation, sidedness (why one side is affected more often), and signs of in‑womb correction. They will use detailed imaging and genetic analyses to connect diet, embryo genetics, and outcomes. Results could guide future human studies on prenatal nutrition and prevention.

Who could benefit from this research

Good fit: People who are pregnant or planning pregnancy and who have a family history of cleft lip or palate, or parents of children with clefts, would be most interested in following this work and in potential future clinical studies.

Not a fit: Because this project uses animal models and lab experiments, it will not provide immediate treatments or direct benefits to babies already born with clefts.

Why it matters

Potential benefit: If successful, the findings could inform prenatal dietary guidance or lead to prenatal interventions that reduce the risk or severity of cleft lip and palate.

How similar studies have performed: Vitamin A has long been linked to cleft risk, but using mouse models to test maternal vitamin A as a modifier and to explore in‑utero correction is relatively new and not yet proven in people.
