The Non-alcoholic Steatohepatitis Clinical Research Network conducted a study involving 234 Hispanic boys and identified SNPs associated with the NAFLD activity score (NAS) on chromosome 8 in the trafficking protein particle complex 9 (TRAPPC9) as well as a region close to actin-related protein 5 associated with fibrosis. Here, TRAPPC9 is linked to metabolic dysfunction-associated steatohepatitis.
