文摘Down syndrome is a leading genetic cause of mental retardation. Here, we show high fractal dimensions and Lempel-Ziv complexity and lower minimum path fractal dimension (P ≤.0006) for the oral vascular networks of patients (n = 14)-and their unaffected parents. This newly rec- ognized sign may provide a useful phenotypical marker for identifying couples potentially at risk for offspring with Down syndrome.
