Senior Director of Marketing and Communications, Meghan Lawlor joined the ALS Therapy Development Institute in 2019. Individuals with C9-ALS/FTD have hexanucleotide repeats in the non-coding region of C9orf72 ranging from 66 to >4400 units in contrast to non-disease individuals carrying 2–30 repeats in the intronic region (Gijselinck et al., 2016; Balendra and Isaacs, 2018). In a study that was recently published in Frontiers in Pharmacology, ALS TDI scientists present evidence implicating previously unexplored therapeutic target for C9ORF72-mediated ALS. Since the mutated gene produces toxic products, blocking the gene with gene therapy might be a useful approach to treatment. Khoury R, Liu Y, Sheheryar Q, Grossberg GT. doi: 10.1242/jcs.256602.

Jeanette Winterson, The ALS Therapy Development Institute is a registered 501(c)3 nonprofit. Please enable it to take advantage of the complete set of features! As a C9orf72 expansion accounts for a significant proportion of sporadic ALS cases as well as familial cases, we wanted to determine whether these findings were limited to C9orf72 ALS cases. Using human induced motor neurons (iMNs), we found that repeat-expanded C9ORF72 … Dr. Vieira noted that the discovery is most immediately relevant for patients who have the C9orf72 mutation, however, the findings may translate to other subtypes of ALS. C9orf72 Research Efforts at ALS Therapy Development Institute The ALS Therapy Development Institute and its scientists are actively focused on the discovery and development of effective treatments for ALS. National Library of Medicine Subscribe to our email list to get the latest updates on ALS research news, events, and clinical trials. It has been recently shown that the most frequent genetic cause of ALS, frontotemporal dementia (FTD), and other neurological diseases is the expansion of a hexanucleotide repeat (GGGGCC) in the non-coding region of the C9ORF72 gene. Type I PRMT inhibition protects against C9ORF72 arginine-rich dipeptide repeat toxicity, findings that ALS TDI scientists published in December of 2019. 8600 Rockville Pike Blocking PKR activation with PKR-K296R or metformin reduces RAN protein levels and improves behavioral and neurologic phenotypes in C9orf72 BAC transgenic mice.

Amyotrophic lateral sclerosis (ALS) is a late-onset neuromuscular disease with no cure and limited treatment options. The discovery in 2011 that the C9orf72 gene mutation can cause both FTD and amyotrophic lateral sclerosis (ALS) has transformed a long held belief that ALS is ‘purely’ a movement disorder and that FTD is ‘purely’ a cognitive or behavioral form of dementia.. eCollection 2020. 2021 Jan 14;14:603023. doi: 10.3389/fnins.2020.603023. 2021 Mar 13;11(3):509. doi: 10.3390/diagnostics11030509.

Patients experience a gradual paralysis leading to death from respiratory complications on average only 2-5 years after diagnosis. Neuron. Nearly 40% of inherited cases of ALS appear to be linked to repeat expansions in the C9ORF72 gene. 2012 Oct;23(5):336-45 “Finding new promising treatments for ALS will require new approaches. Clinicians deal with a genetic testing conundrum. Bethesda, MD 20894, Copyright This is significant because C9orf72 is the most common known mutation found in people with familial ALS, and has also been seen in some cases of sporadic ALS. Metformin is a drug treatment for patients with type 2 diabetes that regulates sugar levels released by the liver. Therapeutic Strategies To date, C9orf72 -associated ALS/FTD has no effective treatment.
