New genetic test may uncover hidden nerve disease in patients with unexplained symptoms

This study tested a new genetic screening approach to find cases of a rare inherited nerve disease called TTR-FAP in 130 patients with chronic neuropathy of unknown cause. The goal was to see how many of these patients actually have TTR-FAP, which is often missed due to varied symptoms. By using a simple blood test to look for TTR gene mutations, researchers hope to speed up diagnosis and allow earlier treatment.
