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.691G>C (p.V231L) alteration is located in exon 7 (coding exon 7) of the MRPL9 gene. This alteration results from a G to C substitution at nucleotide position 691, causing the valine (V) at amino acid position 231 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
