Color Vision Defects
|
D003117 |
[Severely deficient color perception, typically with monochromacy and reduced visual acuity. The atypical form can include normal visual acuity with pseudomonochromacy.
, Defects of color vision are mainly hereditary traits but can be secondary to acquired or developmental abnormalities in the CONES (RETINA). Severity of hereditary defects of color vision depends on the degree of mutation of the ROD OPSINS genes (on X CHROMOSOME and CHROMOSOME 3) that code the photopigments for red, green and blue.

Colorectal Neoplasms, Hereditary Nonpolyposis
|
D003123 |
[A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas.

It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
