Mental retardation, growth retardation, antimongoloid palpebral fold, hypertelorism, high gothic palate, dental anomalies, deformities of nose and ears. Shortening and plumping of finger and toe phalanges. In addition, in more than 50% of cases, there is a nevus teleangiectaticus of the forehead or neck and hypertrichosis of the back. Pilomatrixomas have been described in association.
Of note, several studies have demonstrated an increased keloid tendency for Rubinstein-Taybi syndrome (Jfri A et al 2018). Keloids occur in 24% of individuals with RSTS, either spontaneously or after minor trauma, usually beginning in early puberty (van de Kar AL et al. 2014). Most patients had multiple keloids. The mean age of onset was 11-9 years. The majority of keloids were located on the shoulders and chest (van de Kar AL et al. 2014).
