A crease on the palm of the hand, so called because of its similarity to the transverse flexion crease found in some monkeys. Normally the palm of the hand at birth contains several flexion creases, two of which are separate and approx. transverse. When these two appear to fuse and form a single transverse crease, a simian crease is present. The crease may be present in a variety of developmental abnormalities, including Down syndrome, rubella syndrome, Turner syndrome, Klinefelter syndrome, pseudohypoparathyroidism, and gonadal dysgenesis.See: illustration
