Terminal lung disease has also been reported. The cause of HMD is thought to be an abnormality in desmosomes and gap junctions, which are structures involved in cell-to-cell contact. HMD typically follows autosomal dominant inheritance, but has occurred sporadically (in an individual who has no family history of the condition). Treatment typically focuses on individual symptoms of the condition."

POH can, however, be distinguished clinically by the deep and progressive nature of the heterotopic bone formation."

The thickening of the skin can limit joint mobility and causes joints to be stuck in a bent position (flexion contractures). The onset of signs and symptoms can range from presenting at birth through childhood. Other signs and symptoms may include excessive hair growth (hypertrichosis), loss of body fat (lipodystrophy), scoliosis, muscle weakness, slow growth, and short stature. Weakness or paralysis of the eye muscles have also been reported. Stiff skin syndrome is caused by mutations (changes) in the FBN1 gene and is inherited in an autosomal dominant manner. Diagnosis is based on a clinical evaluation that is consistent with stiff skin syndrome, and the diagnosis can be confirmed with genetic testing. Treatment is based on the symptoms of each individual and may include physical therapy."

It most commonly affects women and symptoms often start around the onset of puberty. Some patients report itching too. It is a form of physical urticaria . The exact underlying cause of aquagenic urticaria is currently unknown. Due to the rarity of the condition, there is very limited data regarding the effectiveness of individual treatments; however, various medications and therapies have been used with variable success."

This disease can present with a variety of symptoms, depending on the size, location, and severity of the affected area. In a minority of patients, cutaneous vasculitis can be part of a more severe vasculitis affecting other organs in the body - this is known as systemic vasculitis."

It is mainly found in females and is characterized by small or poorly developed eyes (microphthalmia) and characteristic linear skin markings on the head and neck. The signs and symptoms of this condition may include abnormalities of the brain, heart, and genitourinary system. Other symptoms may include short stature, developmental delay, and finger and toenails that do not grow normally (nail dystrophy). MLS syndrome is typically caused by either a deletion of certain genetic material on the p (short) arm of the X chromosome or by a mutation in the HCCS gene. In some cases, it may be caused by mutations in the COX7B and NDUFB11 genes, (also located on the X chromosome). According to the mutated gene, the disease may be classified in three subtypes. This condition is inherited in an X-linked manner and is thought to result in serious early developmental concerns in males, leading to almost no males with this condition surviving to delivery.Although there is no specific treatment or cure for MLS syndrome, there may be ways to manage the symptoms. A team of doctors is often needed to figure out the treatment options based on each person's symptoms."
