WebNov 10, 2015 · In addition, our group reported that a missense homozygous mutation [c.424 G > T (p.D142Y)] in the FARS2 gene was the underlying cause of hereditary spastic paraplegia in a Chinese family (7). WebFeb 23, 2024 · This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 309 of the FARS2 protein (p.Gly309Ser). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with FARS2-related conditions (PMID: …

WebJul 6, 2024 · This is consistent with white matter loss in the brain of patients with FARS2 mutations. The strong degeneration of motor neurons in zebrafish, and excessive neuronal death within the motor cortex in Fars2-deficient mouse models, clarified the spastic paraplegia phenotype observed in human patients with FARS2 mutations. This is further ... WebDec 8, 2024 · The primary defects in these FARS2 mutations were the deficient aminoacylation of tRNA Phe (26, 28). The aberrant tRNA Phe metabolism impaired mitochondrial translation and subsequent deficiencies of oxidative phosphorylation (25, 28).
