This project will define how impaired dolichol biosynthesis disrupts glycosylation, protein handling and cellular quality control in DHDDS deficiency. By measuring these processes dynamically with stable isotope tracers and mass spectrometry, the study aims to convert a poorly understood rare disease into a measurable pathway for biomarker discovery, functional diagnostics and therapeutic target identification.
Background
DHDDS deficiency is a rare and devastating congenital disorder of glycosylation. It affects dolichol biosynthesis, a core biochemical pathway required for normal protein glycosylation. Despite this, patients often do not show the classical transferrin isoelectric focusing pattern that usually reveals defective glycoprotein synthesis in CDG.
Hypothesis and aims
We hypothesise that DHDDS deficiency causes a dynamic failure of dolichol driven glycosylation and protein quality control that is not fully captured by conventional CDG testing.
Research outputs
The project will deliver a stable isotope based cellular model of DHDDS deficiency that can measure dolichol flux, glycoprotein synthesis, protein folding, trafficking and degradation in real time.
