Genes affected

RAD54B (HGNC:17228): (RAD54 homolog B) The protein encoded by this gene belongs to the DEAD-like helicase superfamily. It shares similarity with Saccharomyces cerevisiae RAD54 and RDH54, both of which are involved in homologous recombination and repair of DNA. This protein binds to double-stranded DNA, and displays ATPase activity in the presence of DNA. This gene is highly expressed in testis and spleen, which suggests active roles in meiotic and mitotic recombination. Homozygous mutations of this gene were observed in primary lymphoma and colon cancer. [provided by RefSeq, Jul 2008]

The c.2141T>G (p.F714C) alteration is located in exon 12 (coding exon 11) of the RAD54B gene. This alteration results from a T to G substitution at nucleotide position 2141, causing the phenylalanine (F) at amino acid position 714 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
