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.

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 02, 2024	This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1097 of the LARS protein (p.Ile1097Val). This variant is present in population databases (rs745902477, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with LARS-related conditions. ClinVar contains an entry for this variant (Variation ID: 1200949). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Jun 21, 2021	Has not been previously published as pathogenic or benign to our knowledge; In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 27535533) -

The c.3289A>G (p.I1097V) alteration is located in exon 31 (coding exon 31) of the LARS gene. This alteration results from a A to G substitution at nucleotide position 3289, causing the isoleucine (I) at amino acid position 1097 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
