Constraints and rationale for modeling human genes in Ciona

This reasoning chain explains how features of Ciona intestinalis and available genetic tools support modeling certain human monogenic disease genes, but impose critical constraints on what kinds of alleles or phenotypes can be tested. Limitations such as lack of reliable CRISPR knock-in methods, inability to maintain adult knockout lines, and unique features like absence of apoptosis all shape model organism feasibility.
