Switch­ing fo­cus in the brain, re­searchers her­ald a pos­si­ble gene ther­a­py break­through in treat­ing an ul­tra-rare dis­ease

A group of in­ves­ti­ga­tors test­ing a gene ther­a­py for ul­tra-rare cas­es of aro­mat­ic amino acid de­car­boxy­lase de­fi­cien­cy has seen some re­mark­able re­sults in their first group of 7 young pa­tients.

Ac­cord­ing to the study pub­lished in Na­ture on Mon­day, the re­searchers de­cid­ed to take a nov­el ap­proach to tack­le the dis­ease, which so far has re­sist­ed just about every­thing tried against it. The dis­ease is char­ac­ter­ized by a de­fi­cien­cy in AADC, an en­zyme that “cat­alyzes the syn­the­sis of dopamine and sero­tonin from their re­spec­tive pre­cur­sors.”
