Neurodevelopmental Disorder with Dysmorphic Facies and Behavioral Abnormalities (NEDFBA)

NEDFBA is a rare genetic disorder characterized by developmental delay, intellectual disability, speech delay, hypotonia, behavioral abnormalities, and dysmorphic facial features [1]. The condition is often associated with eye anomalies, joint hypermobility, and mild skeletal anomalies of the hands and feet [2].

Common Features:

• Developmental delay
• Intellectual disability
• Speech delay
• Hypotonia (low muscle tone)
• Behavioral abnormalities
• Dysmorphic facial features, including almond-shaped palpebral fissures
• Eye anomalies
• Joint hypermobility
• Mild skeletal anomalies of the hands and feet

Additional Information:

NEDFBA is an autosomal dominant disorder, meaning that a single copy of the mutated gene is sufficient to cause the condition [6]. The disorder has been linked to mutations in the SRSF1 gene on chromosome 17q22 [7].

Based on the search results, here are the signs and symptoms associated with neurodevelopmental disorders with dysmorphic facies and behavioral abnormalities:

• Global developmental delay: Affected individuals have severe global developmental delay with severely impaired intellectual development [2].
• Dysmorphic facies: Common dysmorphic features include coarse facies, broad forehead, synophrys, bushy eyebrows, deep-set eyes, downslanting palpebral fissures, epicanthus, and other distinctive facial features [9].
• Behavioral abnormalities: Affected individuals exhibit behavioral abnormalities, including poor or absent language, impaired language, and unprovoked outbursts of happiness [8].
• Gait disturbance: Some cases may present with gait disturbance, dysmorphic facies, and behavioral abnormalities [4].
• Neurological symptoms: Additional neurological symptoms can include hypotonia, seizures, apnea, autonomic or peripheral neuropathy signs, and other complications that can occur in the first years of life [7].

These symptoms can vary across different cases, but they are commonly associated with neurodevelopmental disorders with dysmorphic facies and behavioral abnormalities.

Diagnostic Tests for Neurodevelopmental Disorder with Dysmorphic Facies and Behavioral Abnormalities

The diagnosis of neurodevelopmental disorders with dysmorphic facies and behavioral abnormalities requires a comprehensive approach. According to search results, it is recommended as a first-tier diagnostic test for patients with intellectual disabilities, neurodevelopmental delays, autism associated with syndromic features [3].

Multidisciplinary Approach

A multidisciplinary team of professionals, including psychologists, psychiatrists, geneticists, and pediatricians, should be involved in the diagnostic process. This approach helps to identify the underlying causes of the disorder and develop an effective treatment plan.

Diagnostic Criteria

The diagnosis requires a thorough evaluation of the individual's medical history, physical examination, and behavioral assessment. The following criteria are often used to diagnose neurodevelopmental disorders with dysmorphic facies and behavioral abnormalities:

• Developmental delay or intellectual disability
• Dysmorphic facial features (e.g., microcephaly, short stature)
• Behavioral abnormalities (e.g., attention deficit hyperactivity disorder, autism spectrum disorder)
• Growth deficits

Diagnostic Tools

Several diagnostic tools can be used to assess the individual's condition. These include:

• Facial Emotion Recognition Tests: Studies have shown that individuals with neurodevelopmental disorders may have difficulty recognizing facial emotions [6].
• Behavioral Assessments: Standardized behavioral assessments, such as the Autism Diagnostic Observation Schedule (ADOS), can help identify behavioral abnormalities.
• Genetic Testing: Genetic testing can be used to identify genetic mutations associated with neurodevelopmental disorders.

Medication Options for Neurodevelopmental Disorder with Dysmorphic Facies and Behavioral Abnormalities

Individuals with neurodevelopmental disorders, such as those characterized by dysmorphic facies and behavioral abnormalities, may benefit from various medication options to manage their symptoms. While there is no cure for these conditions, medications can help alleviate associated problems like epilepsy, sleep issues, or behavioral difficulties.

• Anti-seizure medication: Medications like valproic acid and oxcarbazepine have been used to control seizures in individuals with neurodevelopmental disorders (see [3]). These medications may also be effective in managing other symptoms such as anxiety or mood swings.
• Medication for sleep problems: Certain medications, such as melatonin, can help regulate sleep patterns in individuals with neurodevelopmental disorders (not mentioned in the context).
• Behavioral issues: Medications like risperidone and aripiprazole have been used to manage behavioral symptoms associated with neurodevelopmental disorders (not mentioned in the context).

It's essential to note that medication should be used under the guidance of a qualified healthcare professional, as they can help determine the most effective treatment plan for each individual. Additionally, medications may have varying side effects and interactions, so careful monitoring is necessary.

The differential diagnosis for neurodevelopmental disorders with dysmorphic facies and behavioral abnormalities (NEDDFBA) is a crucial aspect of accurate diagnosis. According to the provided context, NEDDFBA can be distinguished from other conditions through its characteristic features.

• Autism Spectrum Disorder: Individuals with IDDADF (Intellectual Developmental Disorder with Autism and Dysmorphic Facies) may exhibit behavioral abnormalities, including autism spectrum disorder. However, IDDADF is an autosomal recessive neurodevelopmental disorder, whereas NEDDFBA is caused by a heterozygous mutation in the FBXO11 gene [13].
• Silver-Russell Syndrome: A case study reported a 35-year-old man initially diagnosed with Silver-Russell syndrome, who was later found to have Neurodevelopmental Disorder with Dysmorphic Facies and Distal Limb Anomalies (NEDDFL) due to disruption of the BPTF gene [14].
• ADNP Syndrome: ADNP syndrome, also known as Helsmoortel-Van Der Aa syndrome, is a genetic disorder that affects brain development. While it shares some similarities with NEDDFBA, such as developmental delay and intellectual disability, it has distinct features like borderline-to-severe intellectual disability [5].
• Stolerman Neurodevelopmental Syndrome: This highly variable disorder can present with developmental delay, motor and speech delay, but its characteristic features are not explicitly mentioned in the context. However, it is essential to consider this condition in the differential diagnosis due to its overlapping symptoms.
• Other Conditions: The context also mentions other neurodevelopmental disorders, such as SETD2-NDDs (SETD2 Neurodevelopmental Disorders), which can present with intellectual disability, behavioral abnormalities, and macrocephaly. However, these conditions have distinct features that differentiate them from NEDDFBA.

In conclusion, the differential diagnosis for NEDDFBA involves considering
