Table 2 Allele frequency and genotype distribution of I/D polymorphism at ACE locus in TCP patients & control subjects

From: Lack of significant association of an insertion/deletion polymorphism in the angiotensin converting enzyme (ACE) gene with tropical calcific pancreatitis

  1. n, number of individuals; TCP, tropical calcific pancreatitis; FCPD, fibro-calculous pancreatic diabetes; ACE, angiotensin converting enzyme; I/D, insertion/deletion polymorphism at ACE locus figures in parentheses indicate number of individuals; P values are represented on comparison of TCP with FCPD, TCP with controls and FCPD with controls.
