Broken palms on both hands are not necessarily Down’s syndrome, but can also be seen in normal children. A broken palm is a through palm, a common palm print pattern that can be a clinical feature of children with Down syndrome, but can also be seen in normal infants and young children. The main signs of Down syndrome in children are mental retardation, growth retardation, and a peculiar facial appearance, and the through-palm is only one of the secondary features that may be present in the condition and is not a diagnostic basis for the diagnosis. Screening for Down’s syndrome is usually accomplished by performing maternal peripheral serology or fetal chromosome tests during pregnancy. If a child is found to have a through-palm along with abnormalities such as mental retardation, growth retardation and special facial features, he or she may have Down’s syndrome, and should be treated as soon as possible after the diagnosis has been confirmed by a doctor.
