Using mice engineered with a stuttering-linked Gnptab mutation, the researchers identified significantly increased iron accumulation in the striatum, a brain region critical for motor control.The study also found that this excess iron was localized in astrocytes, where it was associated with reduced cell size and complexity. Notably, treatment with an iron-chelating drug improved the animals\u2019 vocalization deficits.","thumbnail_url":"https:\/\/stutteringresearch.org\/wp-content\/uploads\/2026\/03\/2.Iron-link-to-stuttering-1024x1024.png","thumbnail_width":1024,"thumbnail_height":1024}
