VSNL1
VSNL1 Gene: A Gateway to Understanding Neurological Disorders
Description
The VSNL1 gene, located on chromosome 9q33, encodes a protein known as visinin-like 1. Visinin-like proteins play a crucial role in the proper function of the retina, the light-sensitive tissue at the back of the eye. VSNL1 is specifically involved in the visual cycle, a process that allows the eye to adapt to changes in light intensity.
Associated Diseases
Mutations in the VSNL1 gene have been linked to several neurological disorders, including:
- Retinitis pigmentosa (RP): A group of inherited eye diseases that cause progressive vision loss and eventual blindness. Mutations in VSNL1 account for approximately 10% of cases.
- Cone-rod dystrophy (CRD): A type of RP that primarily affects the cone cells in the retina, resulting in impaired color vision and central vision loss.
- X-linked juvenile retinoschisis (XLRS): A rare eye disorder characterized by a splitting of the retina‘s inner layers.

Approximately 1 in 4,000 individuals worldwide are affected by VSNL1-related disorders. This number highlights the significant impact of this gene on human health.
