Inherited retinal disease condition profiles

Achromatopsia condition profile

Achromatopsia is a rare, inherited retinal disorder characterized by the complete or partial absence of cone photoreceptor function, leading to severe visual impairment from birth. Individuals experience extreme light sensitivity, poor visual acuity, and complete color blindness. Retinal Dystrophy Inheritance: Autosomal Recessive

Alagille Syndrome condition profile

Alagille syndrome is a rare genetic condition that can affect multiple parts of the body, most notably the liver and the heart. In people with this syndrome, the liver has fewer bile ducts than normal. Bile ducts are tubes that carry bile, a fluid that helps digest fats, from the liver to the gallbladder and small intestine. Because there are too few of these ducts, bile builds up in the liver, causing liver damage, yellowing of the skin and eyes (jaundice), and severe itching.

Alstrom Syndrome condition profile

Alström Syndrome is a rare, inherited multi-system disorder characterized by progressive vision loss, hearing loss, obesity, and type 2 diabetes. It affects various organs, leading to significant health challenges from early childhood. Syndromic IRD Inheritance: Autosomal Recessive

Autosomal Dominant Optic Atrophy condition profile

Autosomal Dominant Optic Atrophy (ADOA) is a genetic eye condition that causes a slow, gradual loss of vision. It is the most common inherited disorder affecting the optic nerve, which is the cable that sends visual information from the eye to the brain. The condition usually begins in childhood, often before the age of 10, but the vision changes happen so slowly that many people don't notice exactly when they started. In ADOA, the cells in the eye that connect to the optic nerve slowly stop w Optic Neuropathy Inheritance: Autosomal Dominant

Autosomal Dominant Vitreoretinochoroidopathy condition profile

Autosomal Dominant Vitreoretinochoroidopathy, or ADVIRC, is a very rare genetic eye condition that affects how the eye develops and functions. It is caused by a change (mutation) in a specific gene called BEST1, which is responsible for making a protein that helps keep the cells in the back of the eye healthy. In ADVIRC, this protein doesn't work correctly, leading to problems in several parts of the eye, including the clear gel inside the eye (the vitreous), the light-sensitive layer at the bac Vitreoretinal Disorder Inheritance: Autosomal Dominant

Bardet-Biedl Syndrome condition profile

Bardet-Biedl Syndrome (BBS) is a rare, multisystem genetic disorder characterized by retinal degeneration, obesity, intellectual disability, kidney abnormalities, extra fingers/toes (polydactyly), and hypogonadism. It is a ciliopathy, meaning it results from defects in cilia, which are essential cellular structures. Syndromic IRD Inheritance: Autosomal Recessive

Batten Disease condition profile

Batten disease, specifically the juvenile form known as CLN3 disease, is a rare and severe genetic disorder that affects the nervous system. Children with this condition usually grow and develop normally in their early years. However, between the ages of 5 and 15, they begin to experience a rapid and progressive loss of vision. This vision loss is often the first sign of the disease and happens because the light-sensing cells in the eyes slowly stop working. Unfortunately, this eventually leads Macular Dystrophy Inheritance: Autosomal Recessive

Benign Fleck Retina condition profile

Benign fleck retina is a very rare, inherited eye condition that affects the retina, the light-sensitive tissue at the back of the eye. In this condition, an eye doctor looking into the eye will see a striking pattern of tiny, yellow-white spots or "flecks" scattered across the retina. These flecks are caused by a buildup of certain materials in the cells that support the retina, due to a specific genetic change inherited from both parents.

It affects both rod and cone photoreceptors. Retinal Dystrophy Inheritance: Autosomal Recessive

Blue Cone Monochromatism condition profile

Blue Cone Monochromatism (BCM) is a rare, inherited eye condition that affects the retina, the light-sensitive tissue at the back of the eye. In a normal eye, there are three types of cone cells responsible for daylight vision, sharp details, and seeing colors: red, green, and blue cones. In people with BCM, the red and green cones do not work properly, leaving only the blue cones and the rod cells (which are used for night vision) to process light. Because it is passed down on the X chromosome, Stationary Disorder Inheritance: X-Linked Recessive

Bothnia Dystrophy condition profile

Bothnia Dystrophy is a rare, inherited eye condition that causes progressive vision loss. It is most commonly found in the Västerbotten region of northern Sweden. The condition affects the retina, the light-sensitive tissue at the back of the eye, by disrupting the visual cycle—the process that allows the eye to adapt to different light levels. Patients typically experience night blindness from early childhood, meaning they have significant difficulty seeing in low light or dark environments.

It is an inherited disorder, meaning it is passed down from parents to their children. People with Heimler syndrome typically develop hearing loss early in life, often during childhood. They also experience problems with the development of their adult teeth, a condition called amelogenesis imperfecta, which causes the tooth enamel to be thin, discolored, and p Syndromic IRD Inheritance: Autosomal Recessive

Inherited Tritanopia condition profile

Inherited tritanopia, often called blue-yellow color blindness, is a rare genetic condition that affects how you see colors. People with this condition have a specific difficulty distinguishing between certain colors, particularly shades of blue and green, purple and red, and yellow and pink. Sometimes, dark blue can look like black. This happens because the special cells in the back of the eye (the retina) that detect blue light, called blue cones, do not work properly or are missing.

Retinal Dystrophy Inheritance: Autosomal Recessive, X-Linked

Leber Hereditary Optic Neuropathy condition profile

Leber Hereditary Optic Neuropathy (LHON) is a rare genetic eye disease that causes a sudden and painless loss of central vision. It usually affects young adults, most commonly men in their teens or twenties. The condition typically starts with blurry or cloudy vision in one eye, and within a few weeks or months, the second eye also becomes affected. This loss of central vision makes it very difficult to read, drive, or recognize faces, although peripheral (side) vision usually remains intact. Optic Neuropathy Inheritance: Mitochondrial

Malattia Leventinese condition profile

Malattia Leventinese, also known as Doyne Honeycomb Retinal Dystrophy, is a rare, inherited eye condition that affects the retina, the light-sensitive tissue at the back of the eye. It is characterized by the buildup of small, yellowish deposits called "drusen" under the retina. These deposits often form a distinct radial or "honeycomb" pattern. While the drusen usually start forming in early adulthood, most people do not notice any vision problems until they reach their 30s, 40s, or 50s.
