A baby with broken palms does not necessarily have Down’s syndrome; Down’s babies may show broken palms. Broken palm, also known as through hand, is one of the more common palm print patterns in the organism, and it can be found in normal infants and young children. There are individual differences in the pattern of palm lines, which are related to the selective expression of genes and are not specific to Down’s syndrome, so the presence of broken palms does not necessarily mean that the child is Down’s syndrome. The main clinical features of Down’s syndrome are special facial features, accompanied by symptoms such as backward intellectual development, growth retardation and associated malformations, and some children may also have broken palms. It is important to note that if a child is diagnosed with Down’s syndrome, he or she should be actively treated under the guidance of a medical professional, which can improve the prognosis and quality of life of the child.
