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]

The c.65A>T (p.E22V) alteration is located in exon 2 (coding exon 1) of the LARP7 gene. This alteration results from a A to T substitution at nucleotide position 65, causing the glutamic acid (E) at amino acid position 22 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The E22V variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The E22V variant is not observed in large population cohorts (Lek et al., 2016). The E22V variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position where amino acids with similar properties to Glutamic acid are tolerated across species; however, Valine is observed at this position in evolution. In silico analysis predicts this variant is probably damaging to the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -
