Bradyopsia, also known as “Sticky Yellos Syndrome” or “Greenberg’s Syndrome,” is a rare genetic condition that affects a person’s ability to perceive and process visual information. It is characterized by a delay in the ability to adapt to changes in light, particularly when going from a bright to a dark environment or vice versa.

Individuals with bradyopsia experience a slow recovery time for their vision, leading to difficulties in adjusting to changing lighting conditions. This condition can significantly impact a person’s quality of life, making it challenging to see clearly in situations where quick visual adaptation is necessary.

Bradyopsia is caused by mutations in the RGS9BP gene, which is responsible for the normal functioning of photoreceptors in the retina. This gene plays a crucial role in the recovery time of the visual system and helps it to adapt to different lighting conditions. Mutations in the RGS9BP gene disrupt this process, leading to the symptoms of bradyopsia.

The inheritance pattern of bradyopsia is not well understood, but research suggests that it may have an autosomal recessive pattern. This means that both parents must carry a copy of the mutated gene for their child to be affected by the condition. However, additional genes or other genetic factors may also be involved in the development of bradyopsia.

Diagnosing bradyopsia can be challenging, as it is a rare condition and its symptoms can overlap with those of other diseases or conditions. Genetic testing can be helpful in confirming a diagnosis of bradyopsia by identifying mutations in the RGS9BP gene. A thorough evaluation of the patient’s medical history, symptoms, and a comprehensive eye examination may also be necessary.

Currently, there is no cure for bradyopsia, and treatment focuses on managing the symptoms and improving the patient’s quality of life. This may include wearing light-filtering lenses or sunglasses to reduce the impact of bright lights on vision. Genetic counseling and support from advocacy groups can also provide valuable information and support to individuals and their families affected by bradyopsia.

Even with health insurance, patients in the U. S. have a hard time affording their medical care. About one in five working-age Americans with health insurance, and more than half of those without health insurance, reported having trouble paying their medical bills in the last year, according to S. News & World Report.

In conclusion, bradyopsia is a rare genetic condition that affects the visual system’s ability to adapt to changes in light. The RGS9BP gene plays a crucial role in this process, and mutations in the gene can cause bradyopsia. While there is no cure for this condition, support and resources are available for individuals and families affected by bradyopsia to learn more about the condition and find ways to manage its impact on daily life.

Frequency

Bradyopsia is a rare condition caused by mutations in the RGS9BP gene. According to OMIM, only a few articles have been published about this genetic condition.

Other Names for This Condition

Bradyopsia is a genetic condition that is also known by several other names, including:

• Phosphodiesterase 6D (PDE6D) deficiency
• PDE6D-related bradyopsia
• Brady-olfacto-optic Syndrome
• Persistent enfeebled vision, photoreceptor disorder, and olfactory deficit complex
• Optic atrophy 9

These names reflect the various aspects and characteristics of this condition.

Bradyopsia is mainly caused by mutations in the PDE6D gene, which is responsible for encoding a protein necessary for the function of photoreceptor cells in the retina. Without this protein, the photoreceptors are unable to respond properly to light signals, causing a significant decrease in visual acuity and a decreased ability to distinguish colors.

This condition is inherited in an autosomal recessive pattern, which means that both copies of the PDE6D gene must be mutated for the condition to manifest. Individuals who inherit only one copy of the mutated gene are carriers and usually do not experience any symptoms.

Bradyopsia is a rare condition, with an estimated frequency of less than 1 in 1,000,000 individuals. It is typically diagnosed in childhood or adolescence when affected individuals begin to experience visual difficulties in bright light conditions.

In addition to bradyopsia, mutations in the PDE6D gene have also been associated with other rare conditions, such as Joubert syndrome and Senior-Loken syndrome, which affect multiple organ systems including the brain, kidneys, and eyes.
