Abstract:
We report the case of a 16-year-old girl with 1p36 deletion syndrome, who experienced visual loss in both eyes for 2 months because of lamellar cataracts. Mutations on some 1p36 genes in both experimental models and humans may be associated with cataract. This is the first detailed description of acquired juvenile-onset bilateral cataract with 1p36 deletion.

Photoreceptors and Visual Pathways
6.9K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
