ILMN_1727805 captures a single isoform whereas ILMN_1810875 captures almost all isoforms (Fig. 2), suggesting that there may be a monocyte-specific eQTL that does not affect expression of the long isoform captured by ILMN_1727805, and that, therefore, perhaps only the long isoform of SYNGR1 is involved in the aetiology of PBC. The gene discussed is SYNGR1; the disease is primary biliary cholangitis.
