Genes affected

RTF1 (HGNC:28996): (RTF1 homolog, Paf1/RNA polymerase II complex component) This locus may represent a gene involved in regulation of transcription elongation and chromatin remodeling, based on studies of similar proteins in other organisms. The encoded protein may bind single-stranded DNA. [provided by RefSeq, Sep 2010]

Collection Method: clinical testing

The c.97C>T (p.R33W) alteration is located in exon 1 (coding exon 1) of the RTF1 gene. This alteration results from a C to T substitution at nucleotide position 97, causing the arginine (R) at amino acid position 33 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
