Park JC, Kim JM, Jang KH, Lee SY, Kim KT, Kwon EJ, Park SW, Lee HS, Choi HW, Park SY, Choi HJ, Park SJ, Moon SH, Bae SS, Cha HJ. Multiple isogenic GNE-myopathy modeling with mutation specific phenotypes from human pluripotent stem cells by base editors. Biomaterials.2022.282:121419.
Despite the great potential of disease modeling using human pluripotent stem cells (hPSCs) derived from patients with mutations, lack of an appropriate isogenic control hinders a precise phenotypic comparison due to the bias arising from the dissimilar genetic backgrounds between the control and diseased hPSCs. Herein, we took advantage of currently available base editors (BEs) to epitomize the isogenic disease model from hPSCs. Using this method, we established multiple isogenic GNE myopathy disease models that harbor point mutations on the GNE gene, including four different mutations found in GNE myopathy patients. Four different mutations in the epimerase or kinase domains of GNE revealed mutation-specific hyposialylation and hyposialylation dependent gene signature, which was closely correlated to pathological clinical phenotypes. GNE protein structure modeling based on the mutations, addressed these mutation-specific hyposialylation patterns. Furthermore, treatment with a drug candidate currently under clinical trials showed a mutation-specific drug response in GNE myopathy disease models. These data suggest that derivation of multiple isogenic disease models from hPSCs by using genome editing can enable translationally relevant studies on the pathophysiology of GNE myopathy and drug responses.

Abstract
Despite the great potential of disease modeling using human pluripotent stem cells (hPSCs) derived from patients with mutations, lack of an appropriate isogenic control hinders a precise phenotypic comparison due to the bias arising from the dissimilar genetic backgrounds between the control and diseased hPSCs. Herein, we took advantage of currently available base editors (BEs) to epitomize the isogenic disease model from hPSCs. Using this method, we established multiple isogenic GNE myopathy disease models that harbor point mutations on the GNE gene, including four different mutations found in GNE myopathy patients. Four different mutations in the epimerase or kinase domains of GNE revealed mutation-specific hyposialylation and hyposialylation dependent gene signature, which was closely correlated to pathological clinical phenotypes. GNE protein structure modeling based on the mutations, addressed these mutation-specific hyposialylation patterns. Furthermore, treatment with a drug candidate currently under clinical trials showed a mutation-specific drug response in GNE myopathy disease models. These data suggest that derivation of multiple isogenic disease models from hPSCs by using genome editing can enable translationally relevant studies on the pathophysiology of GNE myopathy and drug responses.
