Genes affected

RPL27 (HGNC:10328): (ribosomal protein L27) Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of four RNA species and approximately 80 structurally distinct proteins. This gene encodes a member of the L27e family of ribosomal proteins and a component of the 60S subunit. A splice site mutation in this gene has been identified in a Diamond-Blackfan anemia (DBA) patient. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. [provided by RefSeq, Mar 2017]

This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 42 of the RPL27 protein (p.Leu42Val). 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬† is likely to be tolerated. This variant has not been reported in the literature in individuals affected with RPL27-related conditions. This variant is present in population databases (rs368450548, gnomAD 0.007%). -
