Genes affected

RECQL5 (HGNC:9950): (RecQ like helicase 5) The protein encoded by this gene is a helicase that is important for genome stability. The encoded protein also prevents aberrant homologous recombination by displacing RAD51 from ssDNA. Three transcript variants encoding different isoforms have been found for this gene.

The RECQL5 c.2635G>A variant is predicted to result in the amino acid substitution p.Val879Ile. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.013% of alleles in individuals of European (Non-Finnish) descent in gnomAD, but is not listed in ClinVar. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
