How does the intron-retained RNA isoform mechanistically reduce glucocerebrosidase protein levels and activity?

INVESTIGATING

While the study shows the variant creates intron-retained transcripts that correlate with reduced enzyme activity, the precise molecular mechanism linking aberrant RNA to protein reduction is not explained. This mechanistic gap limits therapeutic target identification.
