Symptoms and Testing information for NPHP1 Gene Joubert Syndrome Type 4 Genetic Test

Joubert Syndrome is a rare genetic disorder that affects the development of the cerebellum, a part of the brain that controls balance and coordination. Among the various genes associated with Joubert Syndrome, mutations in the NPHP1 gene are known to cause Joubert Syndrome Type 4. This specific type of Joubert Syndrome can lead to a range of symptoms that significantly impact the quality of life of those affected. Understanding these symptoms is crucial for early diagnosis and management of the condition. At DNA Labs UAE, we offer a comprehensive NPHP1 Gene Joubert Syndrome Type 4 Genetic Test for individuals and families seeking clarity on this condition. The test is priced at 4400 AED, reflecting our commitment to providing access to advanced genetic testing technologies at a reasonable cost.

Symptoms of NPHP1 Gene Joubert Syndrome Type 4

Joubert Syndrome Type 4, caused by mutations in the NPHP1 gene, manifests through a variety of symptoms that can be observed from infancy or early childhood. These symptoms include:

  • Hypotonia: Decreased muscle tone, making the muscles appear less firm and causing difficulties with posture and movement.
  • Ataxia: Lack of voluntary coordination of muscle movements, leading to unsteady walk and difficulties in tasks requiring fine motor skills.
  • Oculomotor Apraxia: Difficulty in moving the eyes on command, leading to problems with tracking objects or shifting gaze from one point to another.
  • Irregular Breathing Patterns: Especially noted in infancy, these can include episodes of rapid breathing (tachypnea) or abnormally slow breathing (apnea).
  • Intellectual Disability: Varies in severity among individuals, affecting learning abilities and cognitive development.
  • Renal (Kidney) Abnormalities: Problems with kidney function or structure, which can lead to further health complications if not monitored and managed appropriately.
  • Retinal Dystrophy: Progressive dysfunction of the retina, potentially leading to visual impairment or blindness.
  • Molar Tooth Sign: A hallmark feature of Joubert Syndrome observed through MRI, where the cross-section of the brainstem resembles a molar tooth.
