Expression data from skin fibroblasts derived from Setleis Syndrome patients and normal controls

Setleis Syndrome is a rare type of facial ectodermal dysplasia characterized by an aged leonine appearance with puckered skin about the eyes, absent eyelashes on both lids or multiple rows on the upper lids and none on the lower lids, eyebrows that slant sharply upward laterally, and a rubbery feel of the nose and chin. Some of the patients showed bilateral temporal marks superficially like forceps marks and like the lesions seen in focal facial dermal dysplasia. We have evidence that Setleis Syndrome is caused by nonsense mutations in the gene coding for the small bHLH transcription factor known as TWIST2 in Puerto Rican and Omani patients.
