Clinical features of Rubinstein-Taybi syndrome and novel mutation in the CREBBP gene:an analysis of one case
The patient was a girl aged 3 years and 8 months with normal body length and body weight at birth. The girl had feeding difficulty after birth. Her height, body weight, and head circumference were below the 3rd percentile. She had intellectual disability and an unusual facies manifesting as arched shaggy eyebrows, down-slanting palpebral fissures, and broad nasal bridge, but had no a beaked nose, broad thumbs, or big toes. These clinical manifestations were basically consistent with Rubinstein-Taybi syndrome (RSTS). Gene sequencing identified a heterozygous splice site mutation, c.3779T+1G > T, in the CREBBP gene, which did not exist in her parents. Therefore, a definite diagnosis of RSTS was made. The mutation c.3779T+1G > T had not been reported in the Human Gene Mutation Database and was identified as a novel pathogenic mutation. Then the girl was given rehabilitation training for delayed language and motor development. The girl has been followed up for 3 months in the outpatient department, but the effect of rehabilitation treatment has not been evaluated.
