Autosomal recessive congenital stationary night blindness
More than 35 mutations in the TRPM1 gene have been found to cause autosomal recessive congenital stationary night blindness, which is characterized by the inability to see in low light and other vision problems such as nearsightedness (myopia). Mutations in the TRPM1 gene are found in approximately half of all people with this condition.
Most TRPM1 gene mutations change single protein building blocks (amino acids) in the TRPM1 channel and either alter the structure of the channel or prevent the channel from reaching the bipolar cell membrane. As a result, the TRPM1 channel is nonfunctional and prevents bipolar cells from relaying visual signals. The brain does not receive the visual information sent by rods, leading to difficulty seeing in low light.
