Recognizing the Reported Physical and Developmental Features

Understanding the physical and developmental features of this syndrome is essential for managing your child’s daily care. While the name of the syndrome highlights four main issues, the original study by Dr. Crow in 2006 identified a broader range of physical traits and developmental challenges that occurred in the reported family ^[1].

Because there are so few cases, every child’s presentation may be slightly different. However, the features described below provide a roadmap for what you might observe and what specialists may need to monitor.

Facial and Structural Features

Beyond the primary diagnosis, several specific facial features were noted in the original group of children. These features can affect how a child breathes, eats, and sees.

• Blepharophimosis: This is a term for eyelid openings that are abnormally short and narrow ^[2]. It may occur with ptosis (drooping eyelids). It is important to have an ophthalmologist check if the eyelids droop enough to block the child’s visual axis. If ptosis blocks the child’s vision, it can lead to amblyopia (lazy eye) or vision loss if not addressed early ^[3][4].
• Cleft Palate: This is an opening in the roof of the mouth that occurs when tissues don’t fuse properly during development ^[1]. A cleft palate can make it difficult for an infant to create the suction needed for feeding and may cause liquid to come out of the nose (nasal regurgitation) ^[5].
• Choanal Narrowing: This refers to a narrowing of the back of the nasal passages ^[1]. Because infants primarily breathe through their noses, this narrowing can cause noisy breathing, chronic congestion, or difficulty breathing while feeding.

The Impact of Severe Dermatitis

In the original family, the skin was chronically inflamed and “leaky.” This severe dermatitis often appears shortly after birth and can be very difficult to manage ^[1].

The skin serves as the body’s first line of defense. Because children with this syndrome also have agammaglobulinemia (a lack of antibodies), their immune system cannot easily fight off germs that enter through cracked or inflamed skin ^[6][7]. This makes them highly susceptible to secondary bacterial, viral, or fungal skin infections. Care focuses on “barrier repair”—using intensive moisturizers and protective treatments prescribed by a dermatologist to keep the skin intact and reduce the risk of germs entering the body ^[8].

Developmental Expectations

Significant developmental delay and microcephaly (small head size) were prominent features in the original cases ^[1]. The full range and severity of these delays in other children are completely unknown.

• Brain Growth and Head Shape: Microcephaly indicates that the brain is not growing at the expected rate ^[9]. This is often reported alongside craniosynostosis, where the skull bones join together prematurely ^[1]. A craniofacial team will monitor this closely to ensure the brain has as much room as possible to develop.
• Milestones: Children in the original report experienced “global” delays, meaning they took longer to reach milestones in multiple areas, including sitting up, walking, and speaking ^[1]. Children may benefit from early intervention with speech and occupational therapy, which focuses on supporting each child’s communication rather than predicting any specific limitations ^[5][10].
• Daily Functioning: The combination of physical challenges—such as breathing difficulties from choanal narrowing and the energy required to fight off frequent infections—can lead to failure to thrive, where a child struggles to gain weight or grow as expected ^[11][10]. Parents often need to work closely with a nutritionist and a feeding specialist to ensure the child is getting enough calories to support their development.

While these challenges are significant, identifying them early allows your medical team to put supportive measures in place, such as physical therapy, specialized feeding plans, and proactive skin care, to improve your child’s comfort and quality of life.
