Genes affected

RUVBL2 (HGNC:10475): (RuvB like AAA ATPase 2) This gene encodes the second human homologue of the bacterial RuvB gene. Bacterial RuvB protein is a DNA helicase essential for homologous recombination and DNA double-strand break repair. Functional analysis showed that this gene product has both ATPase and DNA helicase activities. This gene is physically linked to the CGB/LHB gene cluster on chromosome 19q13.3, and is very close (55 nt) to the LHB gene, in the opposite orientation. [provided by RefSeq, Jul 2008]

The c.172G>A (p.V58M) alteration is located in exon 4 (coding exon 4) of the RUVBL2 gene. This alteration results from a G to A substitution at nucleotide position 172, causing the valine (V) at amino acid position 58 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
