Genes affected

MRPL9 (HGNC:14277): (mitochondrial ribosomal protein L9) This is a nuclear gene encoding a protein component of the 39S subunit of the mitochondrial ribosome. Alternative splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 8. [provided by RefSeq, Jul 2014]

The c.536A>G (p.N179S) alteration is located in exon 5 (coding exon 5) of the MRPL9 gene. This alteration results from a A to G substitution at nucleotide position 536, causing the asparagine (N) at amino acid position 179 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
