Genes affected
CARS1 (HGNC:1493): (cysteinyl-tRNA synthetase 1) This gene encodes a class 1 aminoacyl-tRNA synthetase, cysteinyl-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. This gene is one of several located near the imprinted gene domain on chromosome 11p15.5, an important tumor-suppressor gene region. Alterations in this region have been associated with Beckwith-Wiedemann syndrome, Wilms tumor, rhabdomyosarcoma, adrenocortical carcinoma, and lung, ovarian and breast cancers. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Aug 2010]
CARS1-AS1 (HGNC:40125): (CARS1 antisense RNA 1)

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 08, 2024The c.709C>T (p.R237W) alteration is located in exon 7 (coding exon 7) of the CARS gene. This alteration results from a C to T substitution at nucleotide position 709, causing the arginine (R) at amino acid position 237 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
