What is Cornelia de Lange Syndrome?

Intellectual and Behavioral Manifestations

Cornelia de Lange syndrome often presents with intellectual impairment and behavioral abnormalities, particularly in severe cases. Individuals with this syndrome may experience difficulties in cognitive functioning, including learning, reasoning, language acquisition, personal care, and social skills. Additionally, they may exhibit behaviors commonly associated with certain forms of autism, such as repetitive actions and self-inflicted harm.


Understanding the Factors Behind Cornelia de Lange Syndrome

Cornelia de Lange syndrome is primarily caused by a mutation in one of the genes: NIPBL, SMC1A, HDAC8, RAD21, or SMC3. These specific genes are responsible for producing a crucial protein called cohesin complex, which plays a vital role in the development of a fetus. However, when a mutation occurs in any of these genes, it disrupts the normal production of the protein. Consequently, this impairment hampers the regulation and organization required during the developmental stages.
