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.
