Description

The HBA2 c.-4C>T variant is located in the 5' untranslated region. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.013% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/16-222908-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
