Treatment for autosomal dominant porencephaly type I is based on the symptoms that an individual is experiencing - for example, treatment of seizures with anticonvulsants. It is particularly important for individuals with this disorder and hypertension to control their blood pressure, as they are at higher risk of stroke. Other stroke prevention treatments include avoiding anticoagulants, smoking, and situations that may lead to head trauma.

Ullrich congenital muscular dystrophy is a form of congenital muscular dystrophy.It is associated with variants of type VI collagen, it is commonly associated with muscle weakness and respiratory problems, though cardiac issues are not associated with this type of CMD. It is named after Otto Ullrich, who is also known for the Ullrich-Turner syndrome.

The prognosis of this sub-type of MD indicates that the affected individual may eventually have feeding difficulties. Surgery, at some point, might be an option for scoliosis.

Scoliosis which is a sideways curve of the persons vertebrate, is determined by a variety of factors, including the degree (mild or severe), in which case if possible a brace might be used by the individual

The type II and XI collagenopathies are a group of disorders that affect connective tissue, the tissue that supports the body's joints and organs. These disorders are caused by defects in type II or type XI collagen. Collagens are complex molecules that provide structure, strength, and elasticity to connective tissue. Type II and type XI collagen disorders are grouped together because both types of collagen are components of the cartilage found in joints and the spinal column, the inner ear, and the jelly-like substance that fills the eyeball (the vitreous). The type II and XI collagenopathies result in similar clinical features.

In 2014 the European Medicines Agency (EMA) granted orphan drug designation to arimoclomol for the treatment of Niemann-Pick type C. This was followed in 2015 by the U.S. Food & Drug Administration (FDA). Dosing in a placebo-controlled phase II/III clinical trial to investigate treatment for Niemann-Pick type C (for patients with both type C1 and C2) using arimoclomol began in 2016. Arimoclomol, which is orally administered, induces the heat shock response in cells and is well tolerated in humans.

There is no known cure for Niemann–Pick type C, nor is there any FDA-standard approved disease modifying treatment. Supportive care is essential and substantially improves the quality of life of people affected by NPC. The therapeutic team may include specialists in neurology, pulmonology, gastroenterology, psychiatrist, orthopedics, nutrition, physical therapy and occupational therapy. Standard medications used to treat symptoms can be used in NPC patients. As patients develop difficulty with swallowing, food may need to be softened or thickened, and eventually, parents will need to consider placement of a gastrostomy tube (g-tube, feeding tube).

An observational study is underway at the National Institutes of Health to better characterize the natural history of NPC and to attempt to identify markers of disease progression.

Since about 2002, some patients with this disorder have been offered drug therapy with bisphosphonates (a class of osteoporosis drugs) to treat problems with bone resorption associated with the bone breakdown and skeletal malformations that characterize this disorder. Brand names include Actonel (risedronate/alendronate), made by Merck Pharmaceuticals. Other drugs include Pamidronate, made by Novartis and Strontium Ranelate, made by Eli Lilly. However, for more progressive cases, surgery and bone grafting are necessary.

Autosomal dominant porencephaly type I is rare and its prevalence and incidence are unknown. It affects males and females equally.

CGL patients have to maintain a strict diet for life, as their excess appetite will cause them to overeat. Carbohydrate intake should be restricted in these patients. To avoid chylomicronemia, CGL patients with hypertriglyceridemia need to have a diet very low in fat. CGL patients also need to avoid total proteins, trans fats, and eat high amounts of soluble fiber to avoid getting high levels of cholesterol in the blood.

No cures for lysosomal storage diseases are known, and treatment is mostly symptomatic, although bone marrow transplantation and enzyme replacement therapy (ERT) have been tried with some success. ERT can minimize symptoms and prevent permanent damage to the body. In addition, umbilical cord blood transplantation is being performed at specialized centers for a number of these diseases. In addition, substrate reduction therapy, a method used to decrease the production of storage material, is currently being evaluated for some of these diseases. Furthermore, chaperone therapy, a technique used to stabilize the defective enzymes produced by patients, is being examined for certain of these disorders. The experimental technique of gene therapy may offer cures in the future.

Ambroxol has recently been shown to increase activity of the lysosomal enzyme glucocerebrosidase, so it may be a useful therapeutic agent for both Gaucher disease and Parkinson's disease. Ambroxol triggers the secretion of lysosomes from cells by inducing a pH-dependent calcium release from acidic calcium stores. Hence, relieving the cell from accumulating degradation products is a proposed mechanism by which this drug may help.

Mutations in the "COL11A1", "COL11A2", and "COL2A1" genes cause collagenopathy, types II and XI. These genes carry instructions for the protein strands that make up type II and type XI collagen. All collagen molecules are made of three protein strands (called alpha chains). The alpha chains may be identical or different, depending on the type of collagen. Type II collagen is made by combining three copies of the alpha chain made by the "COL2A1" gene. Type XI collagen, on the other hand, is composed of three different alpha chains: the products of the "COL2A1", "COL11A1", and "COL11A2" genes.

Mutations in these genes interfere with the proper assembly of type II and XI collagens or reduce the amount of these collagens. Defective or reduced numbers of collagen molecules affect the development of bones and other connective tissues, causing the signs and symptoms of the type II and XI collagenopathies.

Type A Niemann–Pick disease (about 85% of cases) has an extremely poor prognosis, with most cases being fatal by the age of 18 months. Type B (adult onset) and type C (mutation affecting a different molecule) Niemann–Pick diseases have a better prognosis.

Metformin is the main drug used for treatment, as it is normally used for patients with hyperglycemia. Metformin reduces appetite and improves symptoms of hepatic steatosis and polycystic ovary syndrome. Leptin can also be used to reverse insulin resistance and hepatic steatosis, to cause reduced food intake, and decrease blood glucose levels.

Autoimmune polyendocrine syndrome type 1 (APS-1), also known as autoimmune polyendocrinopathy-candidiasis–ectodermal dystrophy/dysplasia (APECED), autoimmune polyglandular syndrome type 1, Whitaker syndrome, or candidiasis-hypoparathyroidism–Addison's disease syndrome, is a subtype of autoimmune polyendocrine syndrome (autoimmune polyglandular syndrome) in which multiple endocrine glands dysfunction as a result of autoimmunity. It is a genetic disorder inherited in autosomal recessive fashion due to a defect in the "AIRE" gene (autoimmune regulator), which is located on chromosome 21 and normally confers immune tolerance.

Sexual dysfunction in diabetics is often a result of physical factors such as nerve damage and/or poor circulation, and psychological factors such as stress and/or depression caused by the demands of the disease.

Long term management is by use of anticonvulsant medication, principally valproate, stiripentol, topiramate or clobazam. Ketogenic diet has also been found useful in certain cases

Management of breakthrough seizures is by benzodiazepine such as midazolam.

Collagen, type II, alpha 1 (primary osteoarthritis, spondyloepiphyseal dysplasia, congenital), also known as COL2A1, is a human gene that provides instructions for the production of the pro-alpha1(II) chain of type II collagen.

Retinoids are used to improve skin manifestations. Retinoids can act on retinoid nuclear receptors and thus regulate transcription. For example, isotretinoin, the most effective drug to treat acne, improves cosmetic features by inducing apoptosis within human sebaceous glands. As a result of this, the increase of connective tissue and hyperplasia of the sebaceous glands is inhibited. Retinoids also decrease procollagen mRNA in fibroblasts, improving pachyderma.

Like retinoids, colchicines can also improve skin manifestations. It is able to bind to the ends of microtubules to prevent its elongation. Because microtubules are involved in cell division, signal transduction and regulation of gene expression, colchicine can inhibit cell division and inflammatory processes (e.g. action of neutrophils and leukocytes). It is suggested that colchicine inhibit chemotactic activity of leukocytes, which leads to reduction of pachydermia.

Use of botulinum toxin type A (BTX-A) improved leonine facies of patients. BTX-A inhibits release of acetylcholine acting at the neuromuscular junction. Furthermore, it blocks cholinergic transmission to the sweat glands and therefore inhibits sweat secretion. However, the exact mechanism for improving leonine faces is unknown and needs to be further investigated.

Autoimmune polyendocrine syndrome type 1 treatment is based on the symptoms that are presented by the affected individual, additionally there is:

- Hormone replacement

- Systemic antifungal treatment

- Immunosuppressive treatment

Kufs disease is one of many diseases categorized under a disorder known as neuronal ceroid lipofuscinosis (NCLs). NCLs are broadly described to create problems with vision, movement and cognitive function. Among all NCLs diseases, Kufs is the only one that does not affect vision, and although this is a distinguishing factor of Kufs, NCLs are typically differentiated by the age at which they appear in a patient

Aside from drug treatments, there are many surgical methods to improve the facial appearance. One of them is facelift, technically known as facial rhytidectomy. This method is a type of cosmetic surgery procedure used to give a more youthful appearance. It involves the removal of excess facial skin and tightening of the skin on the face and neck. A second option is plastic surgery. This is also used for eye drooping.

Some research has suggested breastfeeding decreases the risk in later life and early introduction of gluten-containing cereals in the diet increases the risk of developing islet cell autoantibodies; various other nutritional risk factors are being studied, but no firm evidence has been found.

Giving children 2000 IU of vitamin D daily during their first year of life is associated with reduced risk of type 1 diabetes, though the causal relationship is obscure.

Children with antibodies to beta cell proteins (i.e. at early stages of an immune reaction to them) but no overt diabetes, and treated with niacinamide (vitamin B), had less than half the diabetes onset incidence in a seven-year time span than did the general population, and an even lower incidence relative to those with antibodies as above, but who received no niacinamide.

People with type 1 diabetes and undiagnosed celiac disease have worse glycaemic control and a higher prevalence of nephropathy and retinopathy. Gluten-free diet, when performed strictly, improves diabetes symptoms and appears to have a protective effect against developing long-term complications. Nevertheless, dietary management of both these diseases is challenging and these patients have poor compliance of the diet.

Mandibuloacral dysplasia is a rare autosomal recessive syndrome characterized by mandibular hypoplasia, delayed cranial suture closure, dysplastic clavicles, abbreviated and club-shaped terminal phalanges, acroosteolysis, atrophy of the skin of the hands and feet, and typical facial changes.

Types include:

Short rib – polydactyly syndrome is a family of four closely related dysplasias:

- I - "Saldino-Noonan type"

- II - "Majewski type"

- III - "Verma-Naumoff type" (associated with DYNC2H1)

- IV - "Beemer-Langer type"

According to data from Saxony, Germany, MODY was responsible for 2.4% of diabetes incidence in children younger than 15 years.
