SMAD5 and PCOS/PMOS: a new genetic clue to infertility

Official title: SMAD5 in Polycystic Ovary Syndrome

Funded at Baylor College of Medicine · NIH-11595517 · Data updated 2026-11-12

A research project at Baylor College of Medicine is studying a genetic variant in SMAD5 that may cause a form of PCOS/PMOS and could lead to new ways to diagnose or treat infertility.

Who could benefit from this research

Could help

Women with PCOS/PMOS who have or carry the SMAD5 variant or related AMH/TGFb signaling disruptions.

Less likely to help

Individuals without PCOS/PMOS or without the SMAD5-related pathway involvement may not benefit.

What this research studies

This grant focuses on a genetic variant in SMAD5 that may disrupt signals controlling egg development and ovarian function in women with PCOS/PMOS. Researchers will use mouse models and structural analyses to understand how the SMAD5 change affects the AMH/TGFb signaling pathway that guides follicle growth. The work builds on prior findings and aims to link a human genetic change to a measurable effect in animals and cells, laying groundwork for targeted therapies. The goal is to reveal why some women with PCOS/PMOS experience infertility and how to intervene more precisely in the future.

Why it matters

Potential benefit: If successful, the research could lead to new genetic tests and targeted treatments helping women with PCOS/PMOS improve fertility.

How similar studies have gone: Previous work has linked AMH signaling to PCOS/PMOS, but this project tests a specific SMAD5 variant as a potential causal factor.
