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]

Syndromic X-linked intellectual disability 34 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Rady Children's Institute for Genomic Medicine, Rady Children's Hospital San Diego | - | This frameshifting variant in exon 6 of 12 introduces a premature stop codon and is therefore predicted to result in loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay (NMD). This variant has not been previously reported or functionally characterized in the literature to our knowledge. Loss-of-function variation in NONO is a known mechanism of disease for X-linked syndromic intellectual developmental disorder-34 (MRXS34) (PMID: 26571461, 27329731, 27550220, 32397791). The NONO gene is highly constrained (Z-score= 3.59 and pLI = 0.99), which suggests it is intolerant to variation. The c.731dup (p.Asn244LysfsTer21) variant is absent from the gnomAD population database and thus is presumed to be rare. Analysis of the parental samples was negative for the variant, indicating this variant likely occurred as a de novo event. Based on the available evidence, the c.731dup (p.Asn244LysfsTer21) variant is classified as Pathogenic. - |
