Fig. 3From: In vivo assessment of a single adenine mutation in 5′UTR of Endothelin-1 gene in paediatric cases with severe pulmonary hypertension: an observational studyAssociation of plasma Endothelin-1 levels with different alleles at + 139 position in 5′UTR of edn1 gene.The distribution of ET-1 levels in (a) CHD group and (b) Cyanotic (cyan) and acyanotic (pink) groups is represented for each patient by filled circles (3A/3A), squares (3A/4A) and triangles (4A/4A) and the median value for each group is represented by a horizontal line.
