Chromosome 4p deletion
is a chromosome abnormality
that occurs when there is a missing copy
of the genetic material located on the short arm (p) of chromosome 4
. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 4p deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features.
Most cases are not inherited, but people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person.
