Distinct genomic landscape of colorectal signet ring cell carcinoma reveals frequent KMT2 family alterations and SMAD4 inactivation.
A rare aggressive colon cancer subtype has distinct genetic features, supporting the case for specialized clinical trials and targeted approaches.
This genomic profiling study characterizes colorectal signet ring cell carcinoma, a rare highly aggressive CRC subtype underrepresented in genomic datasets, identifying KMT2 family alterations and SMAD4 loss as frequent molecular features that distinguish it from conventional CRC. These distinct genomic characteristics support the biological basis for subtype-specific clinical trial design and targeted therapeutic development in this poor-prognosis CRC variant.
