Study to Identify the Genetic Variations Associated With Phantom Limb Pain

Henry M. Jackson Foundation for the Advancement of Military Medicine·observational·Posted Oct 31, 2011·Updated Aug 12, 2025

In Brief

An observational study evaluating Blood Draw for Phantom Limb. Completed, enrolled 726 participants across 1 site.

Detailed Summary

The purpose of this study is to determine if there is a genetic component to phantom limb pain. DNA will be analyzed for single nucleotide polymorphisms (SNPs) between the control and phantom limb pain group. Total RNA will also be isolated and profiled to asses the degree to which our gene(s) of interest are expressed in the presence or absence of phantom limb pain. Some proteins, such as inflammatory antibodies or the neurotrophin brain-derived neurotrophic factor (BDNF), will also be assessed for their association(s) with phantom limb pain.
