La malattia di Strumpell, anche conosciuta come paraplegia spastica ereditaria o HSP, rappresenta un gruppo eterogeneo di malattie neurodegenerative caratterizzate da una progressiva spasticità e debolezza agli arti inferiori. Questa malattia è distinta in forme ''pure'' o "complicate'' a seconda della presenza o meno di ulteriori disturbi associati alla spasticità. Geneticamente, la malattia è riportata essere autosomica dominante (AD), autosomica recessiva (AR), o più raramente associata al cromosoma X, anche se casi sporadici sono spesso visti nella pratica clinica. Le forme AD di HSP sono le più frequenti nelle nazioni occidentali, mentre le forme AR di HSP sono le più comuni nel bacino del Mediterraneo. Approssimativamente 50 geni HSP, denominati geni SPG, sono stati localizzati (mappaggio del locus), e circa 20 di essi sono stati identificati chiarendo le basi molecolari di circa il 40-60% delle forme autosomiche. Lo scopo complessivo di questo progetto è di studiare, clinicamente e geneticamente, famiglie con HSP, per ampliare lo spettro di mutazioni geniche, valutarne la relativa frequenza e le manifestazioni cliniche associate, e di utilizzare sia metodiche di laboratorio innovative che indagini molecolari più tradizionali per identificare mutazioni in nuovi geni SPG. L'identificazione di nuovi geni SPG apre la possibilità di studiare le loro funzioni putative, un requisito essenziale per sviluppare approcci terapeutici innovativi.
