Genes affected

RPL10 (HGNC:10298): (ribosomal protein L10) This gene encodes a ribosomal protein that is a component of the 60S ribosome subunit. The related protein in chicken can bind to c-Jun and can repress c-Jun-mediated transcriptional activation. Some studies have detected an association between variation in this gene and autism spectrum disorders, though others do not detect this relationship. There are multiple pseudogenes of this gene dispersed throughout the genome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2015]

The R3H variant in the RPL10 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The R3H variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The R3H variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is conserved across species. Functional studies suggest mutagenesis of the R3 residue reduces the interaction of RPL10 with it's chaperone protein, Sqt1 (Pausch et al., 2015). The R3H variant is a strong candidate for a pathogenic variant -
