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 c.2717C>G (p.S906C) alteration is located in exon 18 (coding exon 17) of the RECQL5 gene. This alteration results from a C to G substitution at nucleotide position 2717, causing the serine (S) at amino acid position 906 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
