Sanjad-Sakati Syndrome
HRD

Sanjad-Sakati Syndrome (SSS), also known as Hypoparathyroidism-Retardation-Dysmorphism Syndrome, is a rare genetic disorder. It primarily affects individuals of Middle Eastern descent, particularly those from the Arabian Peninsula. The syndrome is characterized by a combination of physical, developmental, and endocrine abnormalities, including low levels of calcium in the blood (hypocalcemia) due to underactive parathyroid glands (hypoparathyroidism).

Presentation

Patients with Sanjad-Sakati Syndrome typically present with a range of symptoms. These may include growth retardation, intellectual disability, and distinctive facial features such as a small face, deep-set eyes, and a beaked nose. Other common features include dental anomalies, seizures due to hypocalcemia, and developmental delays. The severity of symptoms can vary widely among individuals.

Workup

Diagnosing Sanjad-Sakati Syndrome involves a combination of clinical evaluation and laboratory tests. Blood tests are crucial to identify hypocalcemia and low parathyroid hormone levels. Genetic testing can confirm the diagnosis by identifying mutations in the TBCE gene, which is responsible for the syndrome. Imaging studies, such as X-rays, may be used to assess bone development and identify any skeletal abnormalities.

Treatment

There is no cure for Sanjad-Sakati Syndrome, but treatment focuses on managing symptoms and improving quality of life. Calcium and vitamin D supplements are commonly prescribed to address hypocalcemia. Seizures, if present, are managed with antiepileptic medications. Early intervention programs, including physical, occupational, and speech therapy, can help address developmental delays and improve functional outcomes.

Prognosis

The prognosis for individuals with Sanjad-Sakati Syndrome varies depending on the severity of symptoms and the effectiveness of treatment. With appropriate management, many patients can lead relatively stable lives. However, ongoing medical care is often necessary to monitor and address complications such as seizures and growth issues. Lifespan may be reduced in some cases due to complications related to the syndrome.

Etiology

Sanjad-Sakati Syndrome is caused by mutations in the TBCE gene, which plays a role in the development and function of the parathyroid glands and other tissues. The syndrome is inherited in an autosomal recessive pattern, meaning that an affected individual must inherit two copies of the mutated gene, one from each parent. Carriers, who have only one copy of the mutation, typically do not show symptoms.

Epidemiology

Sanjad-Sakati Syndrome is a rare disorder, with most reported cases occurring in individuals of Middle Eastern descent. The exact prevalence is unknown, but it is more common in populations with a high rate of consanguinity (marriage between close relatives), which increases the likelihood of inheriting recessive genetic disorders.

Pathophysiology

The pathophysiology of Sanjad-Sakati Syndrome involves the dysfunction of the parathyroid glands, leading to hypoparathyroidism and subsequent hypocalcemia. The TBCE gene mutation affects the production of tubulin-specific chaperone E, a protein essential for normal cellular function. This disruption impacts the development and maintenance of various tissues, contributing to the syndrome's diverse symptoms.

Prevention

Currently, there is no known way to prevent Sanjad-Sakati Syndrome. Genetic counseling is recommended for families with a history of the disorder, especially in communities with high rates of consanguinity. Prenatal genetic testing may be an option for at-risk couples to determine the likelihood of having an affected child.

Summary

Sanjad-Sakati Syndrome is a rare genetic disorder characterized by hypoparathyroidism, developmental delays, and distinctive facial features. It is caused by mutations in the TBCE gene and is most prevalent in Middle Eastern populations. While there is no cure, treatment focuses on managing symptoms and improving quality of life. Early diagnosis and intervention are crucial for optimizing outcomes.

Patient Information

For patients and families affected by Sanjad-Sakati Syndrome, understanding the condition is essential. It is a genetic disorder that affects growth, development, and calcium levels in the body. Symptoms can vary, but with proper medical care and support, individuals can manage the condition effectively. Families are encouraged to seek genetic counseling to understand the inheritance pattern and explore options for family planning.
