While association between SVs and AD status reveals no significant signal, using 1,411 samples in MSBB and ROSMAP, Ming et al. (2021) found that the AD-specific CNVs showed distinct functional annotations compared to MCI-specific and normal-specific CNVs, such as glucuronosyltransferase activity, cellular glucuronidation, and neuron projection. Here, B3GAT2 is linked to Alzheimer disease.
