Transcription and translation of APOL1 variants

It is highly important to document the molecular alterations existing in normal cells prior to the onset of any disease. Knowledge of genetic mutations and associated molecular mechanisms will be helpful for better diagnosis and management of disease. The major focus of this commentary on providing understanding about the apolipoprotein 1 (APOL1) gene, the protein encoded by this gene (apoL1) and the mechanistic details regarding the role of apoL1 in the lysis of Trypanosoma brucei. Information about APOL1 genetic variants, APOL1G1 and APOL1G2, is provided along with the association of these variants with hypertension-attributed end-stage renal disease (ESRD) and focal segmental glomerulosclerosis (FSGS). Moreover, this commentary presents a brief overview of how the authors of a recent Bioscience Reports article [Haque et al (2017) 37, BSR20160531, doi: 10.1042/BSR20160531] have evaluated the functional impact of G1 and G2 alleles on the transcription and translation of APOL1 mRNA.
