Ichthyosis-oral and digital anomalies syndrome is characterized by ichthyosis, unusual facies (small mouth with a thin upper lip and lower lip with a midline groove) and digital anomalies (tapered fingers with a lack of distal flexion creases and wide spacing between the second and third fingers). It has been described in two sibs born to first cousin parents. Transmission appears to be autosomal recessive. The disease is MONDO_0009792 (ichthyosis-oral and digital anomalies syndrome). Also known as: Clayton Smith-Donnai syndrome.
