Children with Down syndrome tend to have a few distinctive physical features such as a flat face and a short neck. They also have some degree of intellectual disability although the severity varies from case to case. But in most cases, it is mild to moderate. In every cell in the human body there is a nucleus, where genetic material is stored in genes. Genes carry the codes responsible for all our inherited traits and are grouped along rod-like structures called chromosomes. Typically, the nucleus of each cell contains 23 pairs of chromosomes, half of which are inherited from each parent. Down…show more content…
It was named after Dr. John Langdon Down who first described it. Prevalence Prevalence of Down syndrome is estimated to be between 1 in 1,000 to 1 in 1,100 live births worldwide. Around 3,000 to 5,000 children are born with chromosome disorder each year and around 250,000 in the USA are affected by Down syndrome. Hearing problems are faced by children suffering from DS in 60 to 80% of the cases. Congenital heart disease is experienced by 40 to 45% of children suffering from DS. Abnormalities with the intestines are also most likely to develop in children with DS. Children suffering from DS also experience more eye problems than others who do not have this disorder. The prevalence of DS at the time of birth increased by 31.1% from 1979 to 2003 in data collected from 10 US regions. Down Syndrome Survival There has been dramatic increase in the life expectancy of people suffering from Down syndrome between 1960 and 2007. People with DS in the 1960s used to live up to the age of 10 years on an average only. The average age of people suffering from DS increased to 47 years in 2007. Around 93% of babies born with the disorder survived till one year of age between 1983 and 2003. About 88% of babies born with DS survived up to 20 years of age during the same period. Decline in the number of infants suffering from DS that die before reaching one year of age has been observed over time. The rate of death in babies
