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]

Ambry Genetics

May 31, 2023

The c.712G>T (p.V238L) alteration is located in exon 7 (coding exon 7) of the MRPL9 gene. This alteration results from a G to T substitution at nucleotide position 712, causing the valine (V) at amino acid position 238 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
