Abstract
OBJECTIVES/GOALS: Understanding the mechanism of transcriptional adaptation may contribute to an explanation for variation in clinical manifestations of Amyotrophic lateral sclerosis patient phenotypes. METHODS/STUDY POPULATION: To examine transcriptional adaptation, we utilized gene editing tools in HT1080 cells and patient samples with known CHCHD10 mutations causative for Amyotrophic lateral sclerosis. Frameshift mutations were performed via CRISPR-Cas9. Ribonucleoprotein electroporation was used to transfect cells and DNA sequencing was conducted to validate gene editing. To validate transcriptional adaption, changes in levels of protein and gene expression will be measured via immunoblot and quantification of CHCHD10 and CHCHCD2 from whole cells lysates of the edited cells. RESULTS/ANTICIPATED RESULTS: We anticipate that CHCHD2 transcriptional adaptation can functionally compensate for the locus loss of function of CHCHD10. This mechanism of transcriptional adaptation may contribute to an explanation for variation in clinical manifestations of patient phenotypes. DISCUSSION/SIGNIFICANCE: Our approach would advance discovery science towards by exploring CHCHD10/2 transcriptional adaptation mechanism that can lead to novel therapies for rare Amyotrophic lateral sclerosis, such as CHCHD10-R15L.
