We analyzed the prevalence of alpha-thalassemia mutations in 298 subjects from Eastern Sicily (Italy) with reduced mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH), normal HbA2 and HbF, and normal serum iron. In 131 subjects (43.9%) we found six different genotypes of alpha-thalassemia: -alpha3.7/alphaalpha (36.6%), -alpha3.7/-alpha3.7 (27.5%), -(MED)/alphaalpha (10.0%), -alpha20.5/alphaalpha (9.1%), alphaHphIalpha/alphaalpha (8.4%), alphaHphIalpha/alphaHphIalpha (6.1%), and -alpha3.7/alphaHphIalpha (2.3%). Our data underline that in Eastern Sicily populations, the molecular screening of alpha-thalassemia mutations and/or deletions may be useful to better characterize the clinically asymptomatic subjects with a slightly reduced MCV and MCH and normal iron status.

Abstract

We analyzed the prevalence of alpha-thalassemia mutations in 298 subjects from Eastern Sicily (Italy) with reduced mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH), normal HbA2 and HbF, and normal serum iron. In 131 subjects (43.9%) we found six different genotypes of alpha-thalassemia: -alpha3.7/alphaalpha (36.6%), -alpha3.7/-alpha3.7 (27.5%), -(MED)/alphaalpha (10.0%), -alpha20.5/alphaalpha (9.1%), alphaHphIalpha/alphaalpha (8.4%), alphaHphIalpha/alphaHphIalpha (6.1%), and -alpha3.7/alphaHphIalpha (2.3%). Our data underline that in Eastern Sicily populations, the molecular screening of alpha-thalassemia mutations and/or deletions may be useful to better characterize the clinically asymptomatic subjects with a slightly reduced MCV and MCH and normal iron status.
