RET-related Hirschsprung disease
Use
Hirschsprung disease (HSCR) is a multi-genic congenital disease of the large intestine characterized by the absence of neuronal ganglia, colon enlargement, and constipation. The RET-related Hirschsprung disease test focuses on the analysis of the RET gene, known to be associated with the condition. This gene sequence analysis aims to identify potential variants that could be pathogenic or likely pathogenic, thereby impacting clinical management of the disease.
Special Instructions
Not provided.
Limitations
The test focuses on detecting variants in the RET gene through high-throughput sequencing techniques such as NGS and may not identify all possible genetic abnormalities associated with Hirschsprung disease. Sequence analysis includes all coding regions and key intronic regions but may not detect all potential intronic and non-coding region mutations. Technical limitations involve insufficient read depth, presence of pseudogenes, and incomplete variant coverage, potentially affecting test accuracy.
