简要总结
GM2 gangliosidoses are a group of autosomal recessive neurodegenerative diseases characterized by a deficiency of the Hex A enzyme to catabolize GM2, thereby causing GM2 accumulation within cellular lysosomes.Hex A is composed of 2 subunits, α- and β-, coded by the HEXA and HEXB genes, respectively. The primary purpose of the current study is to assess the safety and tolerability of TSHA101 administered via IT injection.
