Genes affected

MRPL58 (HGNC:5359): (mitochondrial ribosomal protein L58) The protein encoded by this gene is a peptidyl-tRNA hydrolase and a vital component of the large mitochondrial ribosome. The encoded protein serves as a ribosome release factor for this ribosome, which translates mitochondrial genes. This protein may be responsible for degrading prematurely-terminated polypeptides and for reusing stalled ribosomes. Two transcript variants encoding different isoforms have been found for this gene.

The c.421C>A (p.R141S) alteration is located in exon 5 (coding exon 5) of the MRPL58 gene. This alteration results from a C to A substitution at nucleotide position 421, causing the arginine (R) at amino acid position 141 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
