Definition: The word "achromatosis" is not commonly used, but it refers to a rare genetic disorder that results in an inability to perceive color by sight or by touch. In this case, achromatosis may be associated with mutations in the gene responsible for producing chroma, which is the pigment responsible for distinguishing between blue, green, and red light. The exact cause of achromatosis is not known, but it has been linked to mutations in the genes encoding two types of beta-catenin, a protein involved in cell growth and differentiation. These mutations can result in an inability to produce sufficient levels of this pigment, leading to color blindness or even complete loss of vision. The word "achromatosis" is often used to describe achromatic vision or a visual impairment that affects the perception of blue light only. This condition occurs when there are no chroma genes responsible for producing this pigment, leading to an inability to distinguish between blue and other colors of light. However, it is important to note that achromatosis can also occur in individuals with mutations in the gene encoding beta-catenin or in other genes involved in cell growth and differentiation. Overall, the word "achromatosis" refers to a rare genetic disorder that affects the ability to perceive color by sight or by touch. It is important to note that this condition is not caused by a specific mutation in the chroma gene but rather by mutations in the beta-catenin gene that are responsible for producing chroma, a pigment that helps distinguish between blue, green, and red light.
