Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong
The NM_016065.4(MRPS16):c.332G>A(p.Arg111Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000415 in 1,614,174 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R111P) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Oct 31, 2022 | In 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 submitter | clinical testing | GeneDx | Jun 20, 2017 | p.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). - |
