SOX proteins are transcription factors that are characterized by a common DNA-binding motif known as the HMG domain. We describe the 5. 4-kb human SOX8 gene that codes for a 446-amino-acid protein and that is expressed strongly in brain and less abundantly in other tissues. SOX8 shows an overall identity of 47% to SOX9 and
SOX10
. The latter two possess a C-terminal transactivation domain, whereas in SOX8, this domain is located in the central part of the protein. We have mapped SOX8 within 700 kb of the telomeric repeats of band 16p13.3. Hemizygosity for 1 Mb from this region causes the ATR-16 syndrome characterized by alpha-
thalassemia
and mental retardation. We show that SOX8 is deleted in an ATR-16 patient, and from its location, we deduce that it should be deleted in all previously described cases. Thus, SOX8 is a good candidate gene contributing to the mental retardation phenotype seen in ATR-16 patients.

SOX proteins form a large family of transcription factors related by a DNA-binding domain known as the HMG box. Some 30 Sox genes have been identified in mammals and orthologues have been found in a wide range of other metazoans. Sox genes are highly conserved and are known to play important roles in embryonic development, including roles in gonadal, central nervous system, neural crest and skeletal development. Several SOX genes have been implicated in human congenital diseases. We report here the isolation of Sox8 and its characterisation in mice and humans. This gene has a remarkably similar primary structure and genomic organisation to the campomelic dysplasia gene SOX9 and the Waardenburg-Shah syndrome gene
SOX10
. SOX8 protein is able to bind to canonical SOX target DNA sequences and activate transcription in vitro through two separate trans -activation regions. Further, Sox8 is expressed in the central nervous system, limbs, kidneys, gonads and craniofacial structures during mouse embryo development. Sox8 maps to the t complex on mouse chromosome 17 and to human chromosome 16p13.3, a region associated with the microphthalmia-cataract syndrome CATM and the alpha-
thalassemia
/mental retardation syndrome ATR-16.
