Postnatal short stature is one of the cardinali features of Kabuki Syndrome. It is still unclear as to what extent growth hormone deficiency contributes to this characteristic.
Although birth weight and length are generally normal, growth delay often starts during the first year of life. Poorly coordinated sucking & swallowing, refluxi, recurrent infections, cardiac defects, and hypotonia may all be contributing factors. Although growth hormone levels are in the normal range for most children, a significant number have a partial or complete deficiency. Obesity seems to be a common problem during puberty years. The adult with Kabuki will be shorter than the norm – two or more standard deviations below the mean.
