Genes affected
MRPS16 (HGNC:14048): (mitochondrial ribosomal protein S16) 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 that belongs to the ribosomal protein S16P family. The encoded protein is one of the most highly conserved ribosomal proteins between mammalian and yeast mitochondria. Three pseudogenes (located at 8q21.3, 20q13.32, 22q12-q13.1) for this gene have been described. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 31, 2022In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 214676). This variant has not been reported in the literature in individuals affected with MRPS16-related conditions. This variant is present in population databases (rs141474741, gnomAD 0.05%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 111 of the MRPS16 protein (p.Arg111Gln). -
Uncertain significance, criteria provided, single submitterclinical testingGeneDxJun 20, 2017p.Arg111Gln (CGA>CAA): c.332 G>A in exon 3 of the MRPS16 gene (NM_016065.3). The R111Q variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The R111Q variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant likely does not alter the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. The variant is found in LAPDH-MITOP panel(s). -
