The mutations were found by linkage analysis followed by candidate gene sequencing. Neither mutation was found in 1,942 control individuals. Study of patient lymphoblasts showed that the 598C-G mutation also created an alternative splice site, resulting in an in-frame deletion of 12 codons in exon 6 (delta200-211). The deletion transcript was present at much lower levels in the unaffected father compared to the affected children. Both mutant missense proteins were expressed, could dimerize, and localized to the mitochondria in mammalian cells, but the deletion transcript was poorly expressed, suggesting that it is unstable. Both missense mutations had significantly decreased enzymatic activity compared to wildtype, with the V368L mutation showing a more severe effect. Modeling of the homologous mutations in yeast also indicated that the V368L mutant had a more severe effect on enzyme activity.

<strong>Cloning and Expression</strong>

<span class="mim-text-font">
<p>O'Hanlon et al. (1995) identified the HARS2 gene, which they called HO3, oriented head-to-head with the HARS gene (142810). The deduced 506-amino acid HO3 protein has a calculated molecular mass of 56.9 kD. HO3 shares 72% amino acid identity with HARS. Both proteins contain 3 motifs conserved among class II aminoacyl-tRNA synthetases and 2 signature regions of histidyl-tRNA synthetases. However, HARS and HARS2 have divergent N-terminal domains that are encoded by the first 2 exons of each gene. Northern blot analysis detected a 2.5-kb HO3 transcript that was highly expressed in heart, skeletal muscle, and kidney, with lower expression in brain and liver. </p><p>Using 5-prime RACE with a human kidney cDNA library, O'Hanlon and Miller (2002) identified several HARSL transcripts that differed only in the lengths of their 5-prime UTRs. They also identified HARSL transcripts containing an alternatively spliced 91-bp exon within their 5-prime UTRs. O'Hanlon and Miller (2002) reported that the mouse and human HARSL proteins share 83.9% amino acid identity. They noted that the HARSL protein lacks 60 N-terminal amino acids found in HARS that are necessary for enzymatic activity, suggesting that HARSL may not function as a tRNA synthetase. </p><p>By searching databases for aminoacyl-tRNA synthetases containing a mitochondrial targeting sequence, Bonnefond et al. (2005) identified HARS2, which they called mitochondrial HISRS. The deduced 506-amino acid protein has an N-terminal mitochondrial targeting signal with a predicted cleavage site after residue 34. HARS2 has characteristics of a class II mitochondrial aminoacyl-tRNA synthetase and is expected to function as a dimer. </p><p>Pierce et al. (2011) found high expression of the HARS2 gene in the mitochondria of mammalian cells. </p>

(2011) identified compound heterozygosity for 2 mutations in the HARS2 gene: a paternally inherited 598C-G transversion in exon 6 resulting in a leu200-to-val (L200V) substitution at a highly conserved residue, and a maternally inherited 1102G-T transversion in exon 10 resulting in a val368-to-leu (V368L; 600783.0002) substitution at a highly conserved residue. The mutations were found by linkage analysis followed by candidate gene sequencing. Neither mutation was found in 1,942 control individuals. Study of patient lymphoblasts showed that the 598C-G mutation also created an alternative splice site, resulting in an in-frame deletion of 12 codons in exon 6 (delta200-211). The deletion transcript was present at much lower levels in the unaffected father compared to the affected children. Both mutant missense proteins were expressed, could dimerize, and localized to the mitochondria in mammalian cells, but the deletion transcript was poorly expressed, suggesting that it is unstable. Both missense mutations had significantly decreased enzymatic activity compared to wildtype, with the V368L mutation showing a more severe effect. Modeling of the homologous mutations in yeast also indicated that the V368L mutant had a more severe effect on enzyme activity. Based on the functions of mitochondrial tRNA synthetases and cellular defects resulting from their mutation, Pierce et al. (2011) speculated that mutations in HARS2 result in decreased mitochondrial translation and respiratory chain defects in affected tissues. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
