Also known as:
Comments: The variant is a (GT)n dinucleotide repeat located in the promoter region of the HMOX1 gene. It associated with hospitalization rates for acute chest syndrome in children with sickle cell disease or sickle β0 thalassemia acquired from the Silent Cerebral Infarct Transfusion (SIT) Trial (n=924). The long form (> 25 GT repeats) was found to be linked with increased HbF levels in a SCD cohort from India, but not significantly associated.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
