A case of Robinow–Sorauf syndrome (craniosynostosis-bifid hallux syndrome): The allelic variant of the Saethre–Chotzen syndrome

The clinical classification of Robinow–Sorauf syndrome has changed over the last few decades. Robinow–Sorauf syndrome is characterized by facies similar to those of Saethre–Chotzen syndrome with bifid or partially duplicated halluces. The current outlook is that the ‘Robinow–Sorauf’ families are examples of variable expression of the TWIST mutant phenotype and that the ‘Robinow–Sorauf’ syndrome lies within the spectrum of the Saethre–Chotzen syndrome. We present a case of 19-year-old female patient exhibiting classical clinical and radiological features of Robinow–Sorauf phenotype of Saethre–Chotzen syndrome. A brief review of previously reported cases and nosology has been presented.
