Glycogen storage diseases (GSDs) are a group of autosomal recessive disorders of glucose metabolism.GSDs are caused by congenital deficiency of enzymes in glycogen synthesis or decomposition,which results in glycogen accumulation in organs.According to the types of enzyme deficiency,GSDs can be classified into more than ten types,among which GSD Ⅻ is a super-rare type of GSD.Two brothers with a 5-year age difference presented severe neonatal asphyxia,myasthenia,myocardial damage,anemia,and mental retardation,being GSD Ⅻ homozygous cases with neonatal onset.The results of gene detection showed that nucleotide and amino acid alterations (c.619G>A,p.E207K) of the ALDOA gene existed in the two brothers,being homozygous,and the genotypes in the parents were heterozygous.This article summarized the clinical features,diagnosis,and treatment of GSD Ⅻ,providing reference for exploring the etiology and treatment of severe asphyxia,myasthenia,anemia,and multiple organ damage in neonates after birth.
