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 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NONO. . Gene score misZ 3.5885 (greater than the threshold 3.09). GenCC has associacion of gene with X-linked syndromic intellectual disability, autism, susceptibility to, 15, syndromic X-linked intellectual disability 34.
• BP4: Computational evidence support a benign effect (MetaRNN=0.21308362).

This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 40 of the NONO protein (p.Pro40Arg). 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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). -
