The MTTL1 gene is most often associated with the mitochondrial inheritance pattern, along with other mtRNA and mtDNA genes. [14] Prognosis The prognosis is guarded with a generally progressive disorder. [emedicine.medscape.com]

Favorable prognosis is indicated by preserved action potential preserved R1 or reappearance of R1 after 3 weeks. About 15% of patients will have permanent sequelae. [neuroweb.us]

The prognosis of LS is poor, especially in infancy-onset disease, as most children will die in the first years of life. [clinicaladvisor.com]
