Genes affected
TARS2 (HGNC:30740): (threonyl-tRNA synthetase 2, mitochondrial) This gene encodes a member of the class-II aminoacyl-tRNA synthetase family. The encoded protein is a mitochondrial aminoacyl-tRNA synthetase. Alternative splicing results in multiple transcript variants. A related pseudogene has been identified on chromosome 4.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 06, 2023The c.91T>A (p.W31R) alteration is located in exon 2 (coding exon 2) of the TARS2 gene. This alteration results from a T to A substitution at nucleotide position 91, causing the tryptophan (W) at amino acid position 31 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
