WebDec 23, 2024 · C9ORF72 is the most common cause of familial ALS and familial frontotemporal dementia (FTD). The results, published in Nature Medicine, have the potential to catalyze research into treatments for ALS, FTD and other neurodegenerative diseases. Jonathan Watts, PhD, and Robert H. Brown Jr., DPhil, MD WebRecent literature has found that approximately 40% of familial ALS, 25% of familial FTD, and 90% of familial ALS/FTD cases have a large hexanucleotide repeat (GGGGCC) expansion in a noncoding region of C9orf72. At lower frequency, C9orf72 hexanucleotide repeat expansions have also been observed in individuals with sporadic ALS, FTD, and ALS/FTD.
