Genes affected
LARS1 (HGNC:6512): (leucyl-tRNA synthetase 1) This gene encodes a cytosolic leucine-tRNA synthetase, a member of the class I aminoacyl-tRNA synthetase family. The encoded enzyme catalyzes the ATP-dependent ligation of L-leucine to tRNA(Leu). It is found in the cytoplasm as part of a multisynthetase complex and interacts with the arginine tRNA synthetase through its C-terminal domain. A mutation in this gene was found in affected individuals with infantile liver failure syndrome 1. Alternatively spliced transcript variants of this gene have been observed.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 09, 2023The c.3295C>T (p.R1099C) alteration is located in exon 31 (coding exon 31) of the LARS gene. This alteration results from a C to T substitution at nucleotide position 3295, causing the arginine (R) at amino acid position 1099 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
