Genes affected

RIF1 (HGNC:23207): (replication timing regulatory factor 1) This gene encodes a protein that shares homology with the yeast teleomere binding protein, Rap1 interacting factor 1. This protein localizes to aberrant telomeres may be involved in DNA repair. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Apr 2010]

The c.206C>T (p.S69L) alteration is located in exon 4 (coding exon 3) of the RIF1 gene. This alteration results from a C to T substitution at nucleotide position 206, causing the serine (S) at amino acid position 69 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
