Genes affected

LARS2 (HGNC:17095): (leucyl-tRNA synthetase 2, mitochondrial) This gene encodes a class 1 aminoacyl-tRNA synthetase, mitochondrial leucyl-tRNA synthetase. Each of the twenty aminoacyl-tRNA synthetases catalyzes the aminoacylation of a specific tRNA or tRNA isoaccepting family with the cognate amino acid. [provided by RefSeq, Jul 2008]

Oct 17, 2017

GeneDx

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

p.Ser737Ser in exon 18 of LARS2: This variant is not expected to have clinical s ignificance because it does not alter an amino acid residue and is not located w ithin the splice consensus sequence. It has been identified in 31/65550 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitu te.org; dbSNP rs371382425). -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.2211T>C variant (rs371382425) has not been previously associated with any mitochondrial disorder and is listed in the ClinVar database as likely benign (Variation ID: 227489). This variant is rare in the general population, and is listed in the Genome Aggregation Database (gnomAD) browser with an overall frequency of 0.04% (identified in 52 out of 125,904 chromosomes). However, this variant affects a weakly conserved nucleotide (Alamut software v 2.9), does not alter the amino acid sequence of LARS2 protein, and is not predicted to alter LARS2 mRNA splicing (Alamut software v 2.9). Therefore, the c.2211T>C variant is likely to be benign. -
