GNAL and Dystonia: In Gnal+/- mice, oxotremorine consistently induced abnormal postures such as the extension of hind limbs from the body axis for >10 s, sustained hunched posture with little movements, slow walking with increased hind limb gait, yielding maximal dystonia scores, while only mild motor signs were observed in WT mice (Figure 5H, Supplementary file 1j).
