SOX6

protein-coding

SRY-box transcription factor 6, the group of SRY-box transcription factors|MicroRNA protein coding host genes

Gene summary

This gene encodes a member of the D subfamily of sex determining region y-related transcription factors that are characterized by a conserved DNA-binding domain termed the high mobility group box and by their ability to bind the minor groove of DNA. The encoded protein is a transcriptional activator that is required for normal development of the central nervous system, chondrogenesis and maintenance of cardiac and skeletal muscle cells. The encoded protein interacts with other family members to cooperatively activate gene expression. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Mar 2009]

*SOX6* was first reported in relation to autosomal dominant complex neurodevelopmental disorder in 2020 in a study involving 19 individuals from 17 unrelated families (Tolchin et al.,PMID: 32442410). Individuals with these variants exhibited developmental delay and intellectual disability. Core clinical features included attention deficit hyperactivity disorder (ADHD), mild facial dysmorphism, craniosynostosis, and osteochondromas. Out of the 19 individuals, 14 had de novo variants, while 4 inherited the variant, including 3 siblings from their affected father and 1 individual from an unaffected father with 22% mosaicism for the variant. Given the spectrum of neurodevelopmental features observed, the gene is curated for autosomal dominant complex neurodevelopmental disorder. Seventeen variants (missense, nonsense, frameshift, copy number variants) have been reported in 19 probands in one publication (Tolchin et al.,PMID: 32442410 ) are included in this curation. Most variants were de novo. Functional assays like immunoblotting and electrophoretic mobility shift assay demonstrated that two of the missense variants significantly affect SOX6's ability to localize within the nucleus and bind to target DNA. More evidence is available in the literature, but the maximum score for genetic evidence (12 points) has been reached. In summary, there is definitive evidence supporting the relationship between *SOX6* and autosomal dominant complex neurodevelopmental disorder. This has been repeatedly demonstrated in both research and clinical diagnostic settings and has been upheld over time. This classification was approved by the ClinGen Intellectual Disability and Autism expert panel on September 17th, 2024 (SOP Version 10).

ClinVar Variants & Pathogenicity by Type

Statistics based on transcript NM_001367873.1. Only rare variants are included.

We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.

Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.
