Glucose Phosphate Isomerase Deficiency: High Prevalence of p.Arg347His Mutation in Indian Population Associated with Severe Hereditary Non-Spherocytic Hemolytic Anemia Coupled with Neurological Dysfunction.

This report describes the high prevalence of p.Arg347His pathogenic variant identified in Indian GPI deficient patients with hemolytic anemia and neuromuscular impairment. It suggests that neuromuscular impairment with hemolytic anemia cases could be investigated for p.Arg347His pathogenic variant causing GPI deficiency because of neuroleukin activity present in the GPI monomer which has neuroleukin action at the same active site and generates neuromuscular problems as well as hemolytic anemia.
