MedlinePlus Genetics: 42 Lipoid proteinosis is a condition that results from the formation of numerous small clumps (deposits) of proteins and other molecules in various tissues throughout the body. These tiny clumps appear in the skin, upper respiratory tract, the moist tissues that line body openings such as the eyelids and the inside of the mouth (mucous membranes), and other areas.The first symptom of this condition is usually a hoarse voice, which is due to deposits in the vocal cords. In infancy the hoarseness is expressed as a weak cry. The voice abnormalities persist throughout life and can ultimately cause difficulty speaking or complete loss of speech. Involvement of the throat, tonsils, and lips can result in breathing problems and upper respiratory tract infections. Deposits in the tongue can result in a thick and shortened tongue. They can also thicken the band of tissue that connects the tongue to the bottom of the mouth (frenulum), making it difficult to extend the tongue. The tongue may also have a smooth appearance due to damage to the taste buds.A characteristic feature of lipoid proteinosis is the presence of multiple tiny, bead-like bumps lining the upper and lower eyelids along the lash line. These bumps are known as moniliform blepharosis. They may cause eyeball irritation or itching but generally do not impair vision.The skin and mucous membranes are often fragile in children with lipoid proteinosis, leading to bleeding and scabbing following minor trauma. These problems often first appear in infancy in the mouth and on the face and limbs. Over time, these scabs form blisters and scars. Deposits accumulate in the skin, which causes the skin to become thickened and yellowish in color. Skin damage appears more frequently on areas that experience friction, such as the hands, elbows, knees, buttocks, and armpits. Some people with this condition have hair loss (alopecia) affecting their scalp, eyelashes, and eyebrows.Neurologic features are also common in people with lipoid proteinosis. Affected individuals may have recurrent seizures (epilepsy) or behavioral and neurological problems, which can include headaches, aggressive behaviors, paranoia, hallucinations, short-term memory loss, and absence of fear. These features are thought to be associated with the presence of deposits and an accumulation of calcium (calcification) in areas of the brain called the temporal lobes. The temporal lobes help process hearing, speech, memory, and emotion. The brain abnormalities and neurological features do not always occur together, so the cause of the neurological features is still unclear.Deposits can be found in some internal organs, including the stomach, a section of the small intestine called the duodenum, and the colon. The deposits in these tissues often do not cause any symptoms and may disappear over time. MalaCards based summary: Lipoid Proteinosis of Urbach and Wiethe, also known as lipoid proteinosis, is related to postpartum depression and prosopagnosia, and has symptoms including seizures, hoarseness and thickened tongue. An important gene associated with Lipoid Proteinosis of Urbach and Wiethe is ECM1 (Extracellular Matrix Protein 1), and among its related pathways/superpathways is Vasopressin-like receptors. Affiliated tissues include skin, temporal lobe and tongue, and related phenotypes are thick lower lip vermilion and acne NINDS: 52 Lipoid proteinosis (LP) is a rare disease that affects the skin and the brain. Three distinctive features characterize the disease: a hoarse voice, unusual growths on the skin and mucus membranes, and damage to the temporal lobes or hippocampus of the brain. The symptoms of LP may begin as early as infancy with hoarseness or a weak cry, due to growths on the vocal cords. Skin lesions appear sometime in the next 3 years, leaving acne- or pox-like scars on the face, hands, and mucous membranes. The most characteristic symptom of LP is waxy, yellow, bead-like bumps along the upper and lower edges of the eyelids. Brain damage develops over time and is associated with the development of cognitive abilities and epileptic seizures. Damage to the amygdala, a part of the brain that regulates emotions and perceptions, leads to difficulties in discriminating facial expressions and in making realistic judgments about the trustworthiness of other people. LP is a hereditary disease that equally affects males and females. Nearly a quarter of all reported cases have been in the Afrikaner population of South Africa, but the disease is increasingly being reported from other parts of the world including India. The gene responsible for LP has recently been identified. It performs an unknown function in the skin related to the production of collagen. GARD: 19 Lipoid proteinosis (LP) of Urbach and Wiethe is a rare condition that affects the skin and the brain. The signs and symptoms of this condition and the disease severity vary from person to person. The first sign of LP is usually a hoarse cry during infancy. Damage to the temporal lobes (the portions of the brain that process emotions and are important for short-term memory) occurs over time and can lead to seizures and intellectual disability. Other signs and symptoms may include hair loss, oligodontia, speech problems, frequent upper respiratory infections, difficulty swallowing, dystonia, and learning disabilities. LP is caused by changes in the ECM1 gene and is inherited in an autosomal recessive manner. OMIM®: 57 Lipoid proteinosis of Urbach and Wiethe is a rare autosomal recessive disorder typified by generalized thickening of skin, mucosae, and certain viscera. Classic features include beaded eyelid papules and laryngeal infiltration leading to hoarseness. The disorder is clinically heterogeneous, with affected individuals displaying differing degrees of skin scarring and infiltration, variable signs of hoarseness and respiratory distress, and in some cases neurologic abnormalities such as temporal lobe epilepsy. Histologically, there is widespread deposition of hyaline (glycoprotein) material and disruption/reduplication of basement membrane (summary by Hamada et al., 2002 and Hamada et al., 2003).
