Comments: The c.273G>T (p.Lys90Asn) is a missense variant in the HBA1 gene that results in the substitution of lysine (AAG) with asparagine (AAT) at codon 90. The abnormal Hb variant can be separated and quantified by CE. It was first detected in a heterozygous state in a Chinese proband with normal hematological parameters and clinical phenotype.
