MARS variant associated with both recessive interstitial lung and liver disease and dominant Charcot-Marie-Tooth disease.

ABSTRACT: Aminoacyl-tRNA synthetases (ARSs) are ubiquitously expressed enzymes responsible for charging tRNA with cognate amino acids during protein translation. Non-canonical functions are increasingly recognized, and include transcription and translation control and extracellular signaling. Monoallelic mutations in genes encoding several ARSs have been identified in axonal Charcot-Marie-Tooth (CMT2) disease, whereas biallelic mutations in ARS loci have been associated with multi-tissue syndromes, variably involving the central nervous system, lung, and liver. We report a male infant of non-consanguineous origin, presenting with successive onset of transfusion-dependent anemia, hypothyroidism, cholestasis, interstitial lung disease, and developmental delay. Whole-exome sequencing (WES) revealed com
