Genes affected

TSR2 (HGNC:25455): (TSR2 ribosome maturation factor) The protein encoded by this gene appears to repress the transcription of NF-kappaB and may be involved in apoptosis. Defects in this gene are a cause of Diamond-Blackfan anemia. [provided by RefSeq, Oct 2016]

This sequence change affects codon 46 of the TSR2 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the TSR2 protein. This variant is present in population databases (no rsID available, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with TSR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 2191008). 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. -
