The majority of pathogenic mutations in the neurofibromatosis type I () gene reduce total neurofibromin protein expression through premature truncation or microdeletion, but it is less well understood how loss-of-function missense variants drive NF1 disease. We have found that patient variants in codons 844 to 848, which correlate with a severe phenotype, cause protein instability and exert an additional dominant-negative action whereby wild-type neurofibromin also becomes destabilized through protein dimerization. We have used our neurofibromin cryogenic electron microscopy structure to predict and validate other patient variants that act through a similar mechanism. This provides a foundation for understanding genotype-phenotype correlations and has important implications for patient counseling, disease management, and therapeutics. 履歴 登録 2022年8月12日 - ヘッダ(付随情報) 公開 2023年4月26日 - マップ公開 2023年4月26日 - 更新 2025年5月28日 - 現状 2025年5月28日 処理サイト : RCSB / 状態 : 公開
