Study Reveals Genetic Link to Microcephaly: EXOSC10 Mutations

10/29/2025

Summary

Story summary

A study led by Dr. Tran Tuoc identifies EXOSC10 haploinsufficiency as a genetic factor contributing to primary microcephaly.
Researchers conducted genomic screening of patients with cortical malformations to uncover this genetic link.
Mutations in EXOSC10 cause premature differentiation of neural stem cells, resulting in a smaller cerebral cortex.
The study links RNA degradation to Sonic hedgehog signaling regulation, which contributes to reduced cortical growth.
The work suggests new diagnostic avenues and therapeutic strategies targeting RNA metabolism in neurodevelopmental disorders.
