Mutations in the human TCOF1 gene have been identified in patients with Treacher Collins Syndrome (Mandibulofacial Dysostosis), an autosomal dominant condition affecting the craniofacial region. We report the isolation of the entire mouse Tcof1 coding sequence (3960 bp) by performing a computer-based search for mouse cDNA clones homologous to TCOF1 and generating overlapping RT-PCR products from mouse RNA. Tcof1 is a 1320 amino acid protein of 135 kd with 61.4% identity to TCOF1 and displays repeating motifs enriched for serine- and acidic amino acid-rich regions with potential phosphorylation sites and putative nuclear localization signals. Tcof1 maps to the mouse chromosome 18 region syntenic with human chromosome 5q32-->q33 which contains the TCOF1 locus. Northern blot hybridization indicates Tcof1 expression is ubiquitous in adult tissues and in the embryonic stage, is elevated at 11 dpc when the branchial arches and facial swellings are present in mouse. Our results are consistent with TCOF1 mutations leading to the Treacher Collins syndrome phenotype.
