Protans have difficulties distinguishing between blue and green colors and also between red and green colors. It is a form of dichromatism in which the subject can only perceive light wavelengths from 400 to 650 nm, instead of the usual 700 nm. Pure reds cannot be seen, instead appearing black; purple colors cannot be distinguished from blues; more orange-tinted reds may appear as very dim yellows, and all orange-yellow-green shades of too long a wavelength to stimulate the blue receptors appear as a similar yellow hue. It is hereditary, sex-linked, and present in 1% of males."

        "definition": "Brody myopathy is a hereditary condition that affects the skeletal muscles (muscles used for movement). Symptoms typically begin in childhood and are characterized by muscle cramping and stiffening (myopathy) after exercise or other strenuous activity. These symptoms can worsen in cold temperatures and are usually painless, however, some individuals may have mild discomfort. Some cases of Brody myopathy are caused by mutations in the ATP2A1 gene. The cause of Brody myopathy for individuals not found to have an ATP2A1 gene mutation remains unknown. Brody myopathy is usually inherited in an autosomal recessive manner with a few reported cases of autosomal dominant inheritance. While there is no one treatment for Brody myopathy, certain muscle relaxants, such as dantrolene and blood pressure medications called calcium channel blockers, such as verapamil may be useful. Some researchers suggest that individuals found to have an ATP2A1 gene mutation have a slightly different disorder in which symptoms appear at an earlier age. They use the disease term 'Brody disease' for individuals with an identifiedmutation versus 'Brody syndrome' for those that do not. More research may help clarify whether these are two different disorders or a variation of the same disorder."

Signs and symptoms include severe intellectual disability, problems with movement, and seizures that are difficult or impossible to treat. While the exact cause of bilateral generalized polymicrogyria is not fully understood, it is thought to be due to improper brain development during embryonic growth. Most cases appear to follow an autosomal recessive pattern of inheritance. Treatment is based on the signs and symptoms present in each person."

For example, when an affected individual makes a fist with the right hand, the left hand makes a similar movement. The mirror movements in this disorder primarily involve the upper limbs, especially the hands and fingers. This pattern of movements is present from infancy or early childhood and usually persists throughout life, without other associated signs and symptoms. Intelligence and lifespan are not affected."

Onset is usually in the fourth decade of life and the course lasts about 20 years. Reported clinical manifestations include diarrhea, nausea, autonomic failure (areflexia, weakness), neurogenic bladder and urinary infections. The disorder is caused by truncation mutations of the prion protein gene PRNP (20p13) leading to deposition of prion protein amyloid."

Specific skeletal muscle structural lesions visible on muscle biopsy include actin accumulations, nemaline and intranuclear bodies, fiber-type disproportion, cores, caps, dystrophic features and zebra bodies.

Association with a Hirschsprung's disease is observed in 16% of the cases. Despite a high mortality rate and a lifelong dependence to mechanical ventilation, the long-term outcome of CCHS should be ultimately improved by multidisciplinary and coordinated follow-up of the patients."
