Genes affected

NONO (HGNC:7871): (non-POU domain containing octamer binding) This gene encodes an RNA-binding protein which plays various roles in the nucleus, including transcriptional regulation and RNA splicing. A rearrangement between this gene and the transcription factor E3 gene has been observed in papillary renal cell carcinoma. Alternatively spliced transcript variants have been described. Pseudogenes exist on Chromosomes 2 and 16. [provided by RefSeq, Feb 2009]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. ClinVar contains an entry for this variant (Variation ID: 985055). This variant has not been reported in the literature in individuals affected with NONO-related conditions. This variant is not present in population databases (gnomAD no frequency). This variant, c.84_95dup, results in the insertion of 4 amino acid(s) of the NONO protein (p.His28_Gln31dup), but otherwise preserves the integrity of the reading frame. -
