Genes affected

RUNDC1 (HGNC:25418): (RUN domain containing 1) This gene encodes a protein that contains a RUN (RPIP8, UNC-14 and NESCA) domain and a coiled coil domain. The encoded protein may negatively regulate p53 transcriptional activity. This gene is a potential candidate gene for predisposition to glioma in humans. [provided by RefSeq, May 2017]

The c.473G>C (p.R158P) alteration is located in exon 1 (coding exon 1) of the RUNDC1 gene. This alteration results from a G to C substitution at nucleotide position 473, causing the arginine (R) at amino acid position 158 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
