Cockayne’s syndrome, or Cockayne’s syndrome, is a rare autosomal recessive disorder characterized by short stature, wasting, optic atrophy, and mental retardation. The causes of Cockayne’s syndrome are related to genetic factors. Cockayne’s syndrome is characterized by the onset of the disease after two years of age and developmental delay. As the disease progresses, it spreads to the nervous system, and symptoms such as short stature, optic nerve atrophy, and mental retardation may occur. When Cockayne’s Syndrome is diagnosed, it is important to actively receive targeted treatment from doctors, but each child’s specific situation is different, and the specific treatment plan will vary. Cockayne’s syndrome is difficult to cure, and the goal of treatment is to prolong the child’s life and alleviate suffering.
