for glycogen storage disease type Ia
Glycogen storage disease type Ia is a serious metabolic disorder where the liver cannot properly release stored sugar into the bloodstream, leading to life-threatening low blood sugar and long-term liver damage. Genglycos is a gene therapy designed to deliver a working copy of the G6PC gene directly into liver cells. This one-time treatment aims to restore the liver's ability to manage blood sugar, potentially reducing the constant risk of dangerous hypoglycemia.
