Unlike what observed in the present study, a number of others have noted that adenomatous polyposis coli (APC), cyclin D2 (CCND2), potassium voltage-gated channel, subfamily H (eag-related), member 5 (KCNH5), and runt-related transcription factor 2 (RUNX2) genes were significantly more frequently in ADC compared to SCC [33-36]. The gene discussed is APC; the disease is AIDS dementia complex.
