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]

NONO Gene-Disease associations (from GenCC):

• neurodevelopmental disorder

  Inheritance: XL Classification: DEFINITIVE Submitted by: Ambry Genetics
• X-linked syndromic intellectual disability

• syndromic X-linked intellectual disability 34

  Inheritance: XL Classification: STRONG, SUPPORTIVE Submitted by: Labcorp Genetics (formerly Invitae), Orphanet, G2P

ACMG classification

Our verdict: Likely_benign. The variant received -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.17574915).
• BS2: High Hemizygotes in GnomAdExome4 at 3 XL gene
