Genes affected

PARS2 (HGNC:30563): (prolyl-tRNA synthetase 2, mitochondrial) This gene encodes a putative member of the class II family of aminoacyl-tRNA synthetases. These enzymes play a critical role in protein biosynthesis by charging tRNAs with their cognate amino acids. This protein is encoded by the nuclear genome but is likely to be imported to the mitochondrion where it is thought to catalyze the ligation of proline to tRNA molecules. Mutations have been found in this gene in some patients with Alpers syndrome. [provided by RefSeq, Mar 2015]

Benign:2

Benign, criteria provided, single submitter	clinical testing	Unidad de Genómica Garrahan, Hospital de Pediatría Garrahan	Jul 31, 2024	This variant is classified as Benign based on local population frequency. This variant was detected in 25% of patients studied in a panel designed for Epileptic and Developmental Encephalopathy, Progressive Myoclonus Epilepsy and Abnormal Movements and Neurodegeneration with brain iron accumulation. Number of patients: 23. Only high quality variants are reported. -
Benign, criteria provided, single submitter	clinical testing	GeneDx	Jan 18, 2016	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
