Comments: Association with increased susceptibility to infections in a cohort of SCA children, suggesting a deleterious effect [PMID: 15996936]. Association with enhanced oxidative stress (higher AOPP levels) and with a delayed age of first complication in an independent cohort of SCA, which would rather suggest a protective effect [PMID: 32937882]. Association with lipid (i.e. total cholesterol and low-density lipoprotein cholesterol (LDL-C)) laboratory markers in SCA patients treated with hydroxyurea. Association with hepatic (i.e. globulin), inflammation (i.e. uric acid) and lipid/glycemic (i.e. glucose) laboratory markers in SCA patients not treated with hydroxyurea [PMID: 29619129].

We follow the HGVS sequence variant nomenclature and IUPAC standards.
