связаться с нами Для этого заболевания характерна ассоциация с ожирением, пигментным ретинитом, постаксиальной полидактилией, поликистозом почек, гипогенитализмом и трудностями в обучении, которые обычно возникают через несколько лет после начала заболевания. Клиническая картина может быть различной, хотя у многих пациентов в течение болезни проявляются почти все признаки. Пигментный ретинит является единственным постоянным признаком после детского возраста. BBS также связан с другими тяжелыми признаками, включая диабет, гипертонию, врожденные пороки сердца и болезнь Гиршпрунга.

- Bardet-Biedl Syndrome - INTERNATIONAL (BBS Foundation)
BARDET-BIEDL Syndrome International Connecting people affected by the syndrome of Bardet-Biedl worldwide About BBS FOUNDATION BBS International is a federation that will enable us to collaborate together on a global scale, to unite efforts, to collect and publish information on the disease, to increase network cooperation, to improve research by avoiding unnecessary duplication. Created on 03 October 2020 by 5 countries (France, USA, UK, Italy, Netherlands). Members are active national patient organisations representing patients and their families affected by BBS. Together, they are the voice of approximately 40,000 patients worldwide. « Bardet-Biedl syndrome is a rare disease, but many of you around the world are affected by it or one or more of your children. The announcement of such a diagnosis is hard and one can feel quite alone. Many countries in the world do not have a national association or the information to better understand the disease. This is also why the Federation was created, to break the isolation and answer your questions. You are not alone ! » Join the community and get to know each other !

Bardet-Biedls Syndrom (BBS) kännetecknas av en kombination av synnedsättning, övervikt, extra fingrar och/eller tår, små könsorgan, nedsatt njurfunktion och inlärningssvårigheter. Andra symtom förekommer också. Bardet-Biedls syndrom ingår i en grupp sjukdomar som kallas ciliopatier och orsakas av en skada i de primära cilierna. En primär cilie är ett orörligt utskott, ett slags antenn på cellytan som samordnar många funktioner som är av betydelse för cellfunktioner som rörelse, syn, känsel och cellsignalering. Störd ciliefunktion kan leda till avvikelser i fosterutvecklingen och ge missbildningar i många olika organ. Hos ungefär 80 procent av alla med Bardet-Biedls syndrom har det varit möjligt att påvisa en sjukdomsframkallande mutation. De vanligaste mutationerna finns i BBS1 (23 procent), BBS2 (8 procent) och BBS10 (20 procent). Hittills (2022) finns mutationer rapporterade i 24 olika gener, som alla är inblandade i tillverkning eller reglering av proteiner som är av betydelse för normal cilieformation och funktion.

- Clinical manifestations | BBS Fédération
Clinical MANIFESTATIONS visual disturbance Yeux Almost all children with Bardet-Biedl Syndrome suffer from decreased vision, most often starting around the age of 5-6 years. It starts with a decrease and then a gradual loss of vision at night or when the light is a little dim. The child sees very little in the dark, but this may go unnoticed when he is small. The field of vision gradually narrows at the sides, giving the impression of looking through an increasingly narrow tube (so-called "tubular vision"). The quality of vision deteriorates greatly during adolescence. Sometimes, other ocular manifestations may be associated with it: blurred distance vision (myopia) or distorted vision (astigmatism), both of which can be corrected with glasses, opacification of the crystalline lens (cataract) leading to a progressive decrease in vision, the appearance of abnormal jerky eye movements (nystagmus), problems with colour distinction, etc. Eventually, central vision can also be affected, making the patient visually impaired. The visual disturbances characteristic of Bardet-Biedl syndrome are due to an impairment of the retina, called retinopathy pigmentosa. The retina is the surface of the back of the eye that receives images, much like a photographic film, and transmits them to the brain in the form of electrical signals. OVERWEIGHT Poids Despite a normal birth weight, affected children are almost always significantly overweight from the first year of life. This overweight often evolves into severe obesity, especially in the trunk area. Sometimes the height is smaller than average. ABNORMALITIES OF TOES & FINGERS Doigts There are often, but not in all cases, malformations of the toes and fingers that are smaller than normal (brachydactyly). There are often six fingers and/or six toes instead of five, with the supernumerary finger(s) located next to the fifth finger (the little finger). This is called postaxial polydactyly. In addition, some children have two or more fingers joined together, i.e. not well separated, and connected by a membrane (webbed fingers or syndactyly). ABNORMALITIES OF the genital organs Organes génitaux In boys, the genitals, penis and testicles, are often abnormally small (hypogonadism). In girls, malformations of the genital organs are also possible. The vagina may be closed by a partition, which causes the uterus to expand, often detected before birth (hydrometrocolpos). KIDNEY AND URINARY DEFORMITIES Reins Malformations of the kidneys and urinary tract are very common. They can be serious and, in a significant number of cases, lead to malfunction of the kidneys, whose function is to filter the blood and allow waste products to be eliminated through urine. In people with Bardet-Biedl syndrome, the progressive reduction in kidney function, known as chronic kidney failure, may require the use of an artificial kidney and lead to a kidney transplant. One of the consequences of this kidney damage is an increase in blood pressure (hypertension), which occurs in more than half of adults. Even if there are no kidney malformations, problems can occur in regulating the amount of water in the body. This is manifested by an increase in the volume of urine (regardless of the volume of liquid absorbed), with a frequent need to urinate, as well as by intense thirst (this is called diabetes insipidus). intellectual deficiency & PSYCHOLOGICAL DISORDERS Intellect The intellectual deficit is not always present. When it does exist, it is moderate or rarely severe. Most often, it is limited to learning difficulties that can be aggravated by vision problems. Affected children may also have a delay in language acquisition (they speak later than others), as well as phonation disorders (abnormal way of producing sounds). There may also be hearing loss (hearing loss), which is often mild and goes unnoticed. Psychological or behavioural disorders may appear in some people in the course of their lives. These disorders include emotional instability, frequent tantrums, inappropriate or uninhibited behaviour (with no idea of what is or is not done), with more rarely obsessive-compulsive behaviour (i.e. repetitive actions, such as washing hands very frequently). However, these disorders only affect a few patients and it is not always clear whether they are directly linked to the syndrome. OTHER MANIFESTATIONS Autres Diabetes (too high blood sugar levels) can also set in, as in many obese people. It initially manifests itself by intense tiredness, thirst and hunger, but over time it can lead to serious complications such as kidney failure, an increased risk of heart attacks and infections, nerve damage that can cause loss of feeling in the hands and feet, etc. It can be treated with medication. Very rarely, incoordination of movements can occur, manifesting itself as abnormalities in staggering gait or poorly coordinated hand movements. In rare cases there are malformations of the heart, in particular communication between the different chambers (atria or ventricles) or narrowing of the heart valves (valvular stenoses). Long-term (chronic) constipation, when present, may be due to Hirschsprung's disease, which is a lack of contraction of the large intestine (colon) which leads to its dilation.
- Who we are | BBS Fédération
Who WE ARE With an increasing number of people and groups sharing common goals and working on common activities, it became clear that more could be achieved by working together than each group working alone. The Bardet-Biedl Syndrome International Federation was created to serve as the central body for a network of national associations and other BBS patient support groups. Our OBJECTIVES The main objective of Bardet-Biedl Syndrome International is to create a platform for collaboration between national associations, support groups and networks, people with BBS and their families, and researchers and professionals working on Bardet-Biedl Syndrome. In more detail, the objectives of Bardet-Biedl Syndrome International are as follows : To find and build a network of all associations and families of people with BBS so that they perceive the federation as a reference point for creating a strong and united Bardet-Biedl community Promote, support and stimulate the exchange of knowledge and understanding of BBS at the international level between national associations to avoid unnecessary duplication of resources Coordinate international research efforts by bringing together research institutes and relevant professionals, To facilitate and promote communication between patients, health professionals, researchers and other organisations that support people with BBS.

El síndrome de Bardet-Biedl (SBB) es una enfermedad genética multisistémica poco frecuente en población caucásica (está estimada 1/150.000), caracterizada por una pronunciada variabilidad fenotípica y una gran heterogeneidad genética. Pertenece al grupo de las ciliopatías, causadas por defectos en la estructura y/o función ciliar. El trastorno se trasmite principalmente de manera autosómica recesiva pero se ha detectado herencia oligogénica en algunos casos. Hasta ahora, se han identificado mutaciones en 24 genes diferentes. Este trastorno está caracterizado por una combinación de síntomas clínicos: obesidad, retinopatía pigmentaria, polidactilia post-axial, riñones poliquísticos, hipogenitalismo y trastornos de aprendizaje, muchos de los cuales aparecen muchos años después de la aparición de la enfermedad. La expresión clínica es variable pero muchos de los pacientes manifiestan la mayoría de los síntomas clínicos durante el curso de enfermedad. La retinopatía pigmentaria es el único síntoma clínico constante después la infancia. El SBB puede también estar asociado con otras manifestaciones graves incluida diabetes, hipertensión, cardiopatía congénita y enfermedad de Hirschsprung . El amplio espectro clínico observado en el SBB está asociado a una significativa heterogeneidad genética. Contactador

Contacto A síndrome de Bardet- Biedl, caracteriza-se pela associação de défice visual progressivo, obesidade, polidactilia, problemas renais, hipogenitalismo nos homens e anomalias genito-urinárias na mulher e dificuldades de aprendizagem. Transmite-se de forma autossómica recessiva e foram identificados 24 genes associados a BBS, mas em cerca de 20% a causa ainda é desconhecida. Estima-se uma prevalência de 1/150.000. As manifestações mais frequentes são: Retinite pigmentar de tipo cone e bastonete (>90%). Esta alteração pode não ser identificável até por volta dos 8 anos, quando se inicia diminuição da visão nocturna; aos 20 anos 75% dos doentes perderam completamente a visão. Polidactilia postaxial (dedo supranumerário na metade externa das mãos e /ou pés) ocorre em cerca de 80%. Obesidade (90%) inicia-se na infância e é essencialmente do tronco. Ao nascer o peso é habitualmente normal. Não controlada, podem surgir outros problemas associados: diabetes, hipertensão, hiperlipidemia. Dificuldades de aprendizagem são frequentes (60%), embora na maioria não exista um défice cognitivo significativo. Défice de atenção, processamento lento e traços obsessivos, compulsivos são comuns. Anomalias genitais (60-90%). No sexo masculino manifesta-se por hipogonadismo com pénis e testículos pequenos, criptorquidia, ausência de caracteres sexuais secundários, atraso pubertário, infertilidade. No sexo feminino podem existir malformações genito-urinárias como ausência ou hipoplasia da vagina, útero, trompas, ovários, imperfuração vaginal, fistulas….e também atraso pubertário, amenorreia, diminuição da fertilidade, mas há casos de gravidez Alterações renais (displasia, doença quística…) ocorrem em 50 a 70% dos casos e podem conduzir a falência renal. Foi sugerido como critério de diagnóstico clínico de BBS a presença de 4 das manifestações acima referidas ou 3 delas e mais duas das seguintes: cardiopatia, diabetes, alterações dentárias, hepáticas, intestinais (hirshprung), anosmia (ausência de cheiro),braquidactilia/sindactilia (dedos curtos/unidos), descoordenação motora/ ataxia, atraso global de desenvolvimento, atraso da linguagem
