Mutation near the binding interfaces at α-hemoglobin stabilizing protein is highly pathogenic.

ABSTRACT: Aggregation of free alpha-hemoglobin proteins forms harmful reactive oxygen radicals during the development of normal erythroid cell, which can be prevented by a chaperone, alpha hemoglobin stabilizing protein (AHSP). Mutations at the AHSP gene may affect its interacting ability with other globin proteins. Various state-of-the-art tools have been extensively used to identify the most deleterious nsSNPs at the AHSP and their pathogenic effect during AHSP-globin interaction. Comprehensive analysis revealed that the V56G of the AHS protein is the most pathogenic amino acid substitution, agreed consistently and significantly (P=1.27E-13) by all the state-of-the-art tools (PROVEAN <-2.5, SIFT=0, SNAP2 >50, SNPs&GO >0.5, PolyPhen >0.5, FATHMM >0.6, PANTHER <-3, VEST P<0.05) and pro
