Abstract

Abstract

En 中文
• Jamuar Syndrome is an ultrarare disorder caused by variants in the essential gene UGDH • UGDH variants may not alter protein expression but profoundly impact development • Disrupted allosteric control of UGDH in C-terminal variants blunts glycan production • Three novel UGDH variants of undetermined significance were validated in the study
