Genes affected

LARP7 (HGNC:24912): (La ribonucleoprotein 7, transcriptional regulator) This gene encodes a protein which is found in the 7SK snRNP (small nuclear ribonucleoprotein). This snRNP complex inhibits a cyclin-dependent kinase, positive transcription elongation factor b, which is required for paused RNA polymerase II at a promoter to begin transcription elongation. A pseudogene of this gene is located on chromosome 3. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2012]

This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 12 of the LARP7 protein (p.Met12Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with LARP7-related conditions. 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
