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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.887

Dec 17, 2023

The c.826G>C (p.D276H) alteration is located in exon 3 (coding exon 3) of the RUNDC1 gene. This alteration results from a G to C substitution at nucleotide position 826, causing the aspartic acid (D) at amino acid position 276 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
