-
A rare genetic progeroid syndrome with a variable phenotype including postnatal growth delay, severe global developmental delay, hypotonia, non-specific dysmorphic facies with aged appearance and cryptorchidism, as well as cardiac arrhythmia and skeletal anomalies. Patients typically present with widely opened fontanelle, mainly truncal hypotonia, waddling gait with hypertonia of the extremities, small hands and feet, broad great toes, scoliosis and redundant skin with lack of subcutaneous fat. There is evidence this disease is caused by mutation in the NAA10 gene on chromosome Xq28.
