2q37 Deletion Syndrome

Diagram of autosomal dominant inheritance.

2q37 Deletion Syndrome is a rare genetic disorder caused by a deletion of a segment on the long arm (q) of chromosome 2. This condition is characterized by a variety of physical, developmental, and behavioral features.

Genetic Basis

2q37 Deletion Syndrome is caused by a deletion of genetic material on chromosome 2 at the q37 location. The size of the deletion can vary among individuals, leading to a range of symptoms. The syndrome is typically not inherited but occurs as a de novo mutation. However, in some cases, it can be inherited in an autosomal dominant manner if a parent carries a balanced translocation involving chromosome 2.

Clinical Features

Individuals with 2q37 Deletion Syndrome may present with:

• Developmental delay and intellectual disability
• Distinctive facial features, such as a prominent forehead, thin upper lip, and a flat nasal bridge
• Short stature
• Brachydactyly (short fingers and toes)
• Hypotonia (reduced muscle tone)
• Behavioral issues, including autism spectrum disorder and attention deficit hyperactivity disorder (ADHD)

Diagnosis

Diagnosis of 2q37 Deletion Syndrome is typically made through genetic testing, such as chromosomal microarray analysis or karyotyping, which can identify the deletion on chromosome 2. Clinical evaluation and assessment of symptoms also play a crucial role in diagnosis.

Management

There is no cure for 2q37 Deletion Syndrome, and treatment is symptomatic and supportive. Management may include:

• Early intervention programs and special education to address developmental delays
• Physical therapy to improve muscle tone and motor skills
• Behavioral therapy to manage behavioral issues
• Regular monitoring by a multidisciplinary team of healthcare providers

Prognosis

The prognosis for individuals with 2q37 Deletion Syndrome varies depending on the severity of symptoms and the size of the deletion. With appropriate support and interventions, many individuals can lead fulfilling lives.
