CTCF

Clinical Characteristics

Every person with CTCF-related disorder (CRD) is unique. The condition affects each individual differently, even in the same family. Some people may have more challenges, while others may have milder features.

Here are some of the more common features seen in CRD:

•    Learning and developmental differences — most individuals take longer to reach developmental milestones (such as sitting, walking, or speaking) and may have learning disabilities.
•    Speech and language delays — many children with CRD are late to talk or may need support with communication.
•    Behavioral differences — these may include:
o    Social communication differences
o    Attention difficulties
o    Sleep challenges
o    Traits seen in autism spectrum disorder

•    Muscle tone differences — low muscle tone (called hypotonia) can make it harder to build strength and coordination.
•    Feeding difficulties — common in infancy or early childhood, sometimes requiring feeding therapy or nutritional support.
•    Growth differences — some individuals are smaller than average in height, weight, or head .
•    Facial features — there may be subtle facial differences, but these do not cause medical problems.
•    Body systems — some individuals may have differences affecting the heart, kidneys, bones, or other parts of the body. Regular check-ups help monitor these areas.

No two individuals with CRD are the same. Some people will have only a few of these features, while others may experience more.
