Seckel syndrome 6

Description

Seckel Syndrome 6: A Rare Autosomal Recessive Disorder

Seckel syndrome 6 (SCKL6) is a rare autosomal recessive disorder characterized by proportionate dwarfism of prenatal onset, low birth weight, growth retardation, severe microcephaly, and delayed speech and language development [3]. It is caused by homozygous mutation in the CEP63 gene on chromosome 3q22 [1].

Clinical Features

The clinical features of Seckel syndrome 6 include:

  • Abnormality of the musculoskeletal system
  • Primary microcephaly
  • Delayed speech and language development
  • Growth retardation
  • Low birth weight

[2, 5]

Physical Characteristics

Individuals with Seckel syndrome 6 may have a small head, narrow bird-like face with a beak-like nose, large eyes, and proportionate dwarfism [9].

Prevalence and Inheritance

Seckel syndrome 6 is an extremely rare form of primordial autosomal recessive dwarfism. It is inherited in an autosomal recessive manner, meaning that the disorder occurs when an individual inherits two copies of a mutated gene, one from each parent.

Signs and Symptoms

Seckel Syndrome Signs and Symptoms

Seckel syndrome, also known as microcephalic primordial dwarfism, is a rare congenital disorder characterized by several distinct signs and symptoms.

  • Intrauterine growth retardation: Slow growth during fetal development can lead to low birth weight.
  • Dwarfism: Postnatal growth retardation results in short height (dwarfism) with arms and legs that are proportionate to height.
  • Microcephaly: A very small head is a characteristic feature of Seckel syndrome.
  • Intellectual disability: Individuals with Seckel syndrome often experience intellectual disability.
  • Unique facial features: Large eyes, beak-like nose, narrow face, and receding lower jaw are some of the distinctive facial features associated with Seckel syndrome.

These symptoms can vary in severity and may not be present in all individuals with Seckel syndrome. Early detection and diagnosis are crucial for providing appropriate care and management.

Additional Symptoms

  • Microcephaly
  • Intellectual disability
  • Unique facial features
  • Intrauterine growth retardation
  • Dwarfism

Diagnostic Tests

Diagnostic Tests for Seckel Syndrome

Seckel syndrome can be diagnosed through various tests, including:

  • Physical Examination: The diagnosis is based almost exclusively on physical symptoms [7]. A healthcare provider will examine the individual to look for characteristic features such as microcephaly, short stature, and unique facial features.
  • Genetic Testing: Molecular genetic testing may show mutations in genes that help in the diagnosis of Seckel syndrome [10]. This test can identify gene mutations associated with the condition.
  • Gene Panel: A PCP (Primary Care Physician) can order a gene panel to test for all the genes associated with Seckel syndrome at once [1].
  • Molecular Genetic Testing: Gene mutations can also be identified by performing molecular genetic tests, helping diagnose Seckel syndrome [8].

It's worth noting that there is currently no lab or genetic test specific to Seckel syndrome. In some cases, a definitive diagnosis cannot be made until the child gets older and the characteristic symptoms appear.

Treatment

Treatment Options for Seckel Syndrome

Seckel syndrome, also known as bird-headed dwarfism, is a rare genetic disorder that affects various aspects of an individual's life. While there is no cure for this condition, treatment options are available to manage its symptoms and associated complications.

  • Supportive Care: The primary focus of treatment is on providing supportive care to alleviate the symptoms and improve the quality of life. This includes managing hematological problems such as leukemia and anemia through appropriate medication and therapy [9].
  • Surgical Treatment: Surgical interventions may be necessary in cases where skin ulcers or other complications arise [7].

It's essential to note that treatment for Seckel syndrome is largely symptomatic, with a focus on addressing the associated hematological problems and managing any surgical complications. However, there are ongoing research efforts to explore potential therapeutic options.
