What is the prognosis and life expectancy for individuals with chromosome 1, monosomy 1q4?

It is difficult to predict the long-term outlook for children with 1q4 deletions because in many cases, this chromosome disorder has been diagnosed with certainty in recent years, and very few adults with the condition have described. It is generally expected that most children will need lifelong care and medical support.[1] Furthermore, prognosis and life expectancy varies with each individual, based on both how mildly or severely affected the individual is, and which signs and symptoms are present.
