Genes affected

SOX4 (HGNC:11200): (SRY-box transcription factor 4) This intronless gene encodes a member of the SOX (SRY-related HMG-box) family of transcription factors involved in the regulation of embryonic development and in the determination of the cell fate. The encoded protein may act as a transcriptional regulator after forming a protein complex with other proteins, such as syndecan binding protein (syntenin). The protein may function in the apoptosis pathway leading to cell death as well as to tumorigenesis and may mediate downstream effects of parathyroid hormone (PTH) and PTH-related protein (PTHrP) in bone development. The solution structure has been resolved for the HMG-box of a similar mouse protein. [provided by RefSeq, Jul 2008]

The p.Phe66Leu variant is de novo, it is absent in population databases and it involves a higly conserved residue in the HMG box DNA-binding domain of the protein. Three further patients were identified with de novo missense variants affecting the HMG box DNA-binding domain of SOX4. Intellectual disability and similar facial dysmorphisms were present in all four. Functional assays demonstrated that SOX4 proteins carrying these four variants are unable to bind DNA in vitro and transactivate SOX reporter genes in cultured cells. -
