Simian crease incidence and the correlation with thenar and hypothenar pattern types in Swedish patients with trisomy 21 (Down's syndrome).

abstract：OBJECTIVES:In recent years, several studies have shown that populations from cold, high-latitude regions tend to have relatively shorter limbs than populations from tropical regions, with most of the difference due to the relative length of the zeugopods (i.e., radius, ulna, tibia, fibula). This pattern has been explai...
