I'm sorry, but I don't have access to my training data, which includes specific articles or their titles. However, you can easily find articles related to CHOK1 karyotyping or idiograms by searching in scientific databases like PubMed, Google Scholar, or other biology-related journals. Use keywords like "CHOK1 karyotyping," "CHOK1 idiogram," or variations of those terms to narrow down your search and find relevant research articles on the topic.
