Exaggerated neurogenic inflammation has been recognized to be one reason for many CRPS symptoms. Since angiotensin-converting enzyme (ACE) is a key enzyme for the termination of neurogenic inflammation, it has been selected as a candidate gene for CRPS predisposition. A previous report of an insertion/deletion (I/D) polymorphism in intron 16 within the ACE gene implicated an increased risk to develop CRPS I associated with the D allele. However, in the present study the D allele frequency was not increased in CRPS I cases (0.51 for D allele, 0.49 for I allele). Furthermore, there was no co-segregation of any genotype (DD, ID, II) with the CRPS phenotype in 12 selected familial CRPS I cases from six CRPS I families. In conclusion, the results presented herein render this particular ACE gene polymorphism unlikely to be a predisposing factor for CRPS I.
