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 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

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. 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.75_86dup, results in the insertion of 4 amino acid(s) of the NONO protein (p.Gln25_His28dup), but otherwise preserves the integrity of the reading frame. -
