PARS2-associated mitochondrial disease: A case report of a patient with prolonged survival and literature review.

ABSTRACT: Biallelic pathogenic variants in mitochondrial aminoacyl-tRNA synthetase (mt-aaRS) PARS2 are associated with mitochondrial cytopathy. Here, we report the tenth case of an individual with biallelic PARS2 pathogenic variants, detected by exome sequencing (ES), and a literature review of ten cases of PARS2 mutations. Our patient displayed symptoms and clinical and laboratory findings similar to those reported previously with normal lactate levels. These symptoms included seizure disorder (which was managed with antiepileptics), developmental delay, and progressive cardiomyopathy which manifested at 19 years of age. The patient received a vitamin regimen including antioxidants as part of his treatment regimen. While further studies are required to conclusively establish th
