Based on limited published evidence, ZC3HAV1L is a cytosolic protein whose function remains largely uncharacterized. The gene is located on chromosome 7 and has been identified in a risk score system for colon cancer prognosis 1. ZC3HAV1L is notable for forming an interchromosomal chimeric transcript with CHMP1A through trans-splicing in normal human cells and tissues, with three variants detected, suggesting involvement in complex splicing mechanisms 2. No direct functional studies of ZC3HAV1L itself have been published.
