ENAH and systemic lupus erythematosus: We observed elevated expression of variable regions of heavy and light chain and constant heavy chain region of Ig gene transcripts in all SLE patient subsets with highest distribution in anti-dsDNA+ patients than in anti- ENA+ patients and lowest in anti-dsDNA+ENA+ patients (Table 6) which is in concordance with the variation of PC related transcripts in each SLE subsets.
