Is Pouch Specific to Colon and Not Ileum?

Abstract

Background: Congenital Pouch Colon (CPC) is an anorectal anomaly with an incidence of 3.5:1 in males and females, respectively. We have earlier reported CPC to be quite prevalent in north Indian tertiary care centers.

Objective: In this article, we deliberate on the possible causes associated with CPC bringing the manifestation of the disease. In addition, we throw insights on the effective role of this congenital anomaly in Colon and provide systems genomic evaluation by comparing our recent analysis to that of Colon and Ileum based on Next-Generation Sequencing (NGS) studies.

Conclusion: In this commentary article, we argue that a host of epigenetic factors could be the reason why the disease is manifested in colon alone. We further hypothesize on the few unmet challenges linking epigenetics to understand the genetic variants.
