Part of the α-thalassemia haplotype results by SNP (family 1). Position 22597 is the maternal mutation site of αα^cs. Between the solid horizontal lines is the area of the SEA deletion. Between the double horizontal lines is the area of -α^3.7 deletion. The deep red background indicates the paternal affected haplotype (-α^3.7). The bright red background indicates one of the maternal affected haplotypes (--^SEA). The pink background indicates the other maternal affected haplotype (αα^cs). “?” represents that the site is not detected
