Genes affected

MRPS9 (HGNC:14501): (mitochondrial ribosomal protein S9) Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within the mitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. They have an estimated 75% protein to rRNA composition compared to prokaryotic ribosomes, where this ratio is reversed. Another difference between mammalian mitoribosomes and prokaryotic ribosomes is that the latter contain a 5S rRNA. Among different species, the proteins comprising the mitoribosome differ greatly in sequence, and sometimes in biochemical properties, which prevents easy recognition by sequence homology. This gene encodes a 28S subunit protein. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.116A>C (p.Q39P) alteration is located in exon 1 (coding exon 1) of the MRPS9 gene. This alteration results from a A to C substitution at nucleotide position 116, causing the glutamine (Q) at amino acid position 39 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
