OBJECTIVE
Mutations in the MERTK gene are responsible for retinal degeneration in the Royal College of Surgeons (RCS) rat and are a cause of human autosomal recessive retinitis pigmentosa (RP). This study reports the identification and functional analysis of novel MERTK mutations to provide
OBJECTIVE
To evaluate the clinical and electrophysiologic findings in a family with two heterozygous sequence changes in the peripherin-retinal degeneration slow (RDS) gene.
METHODS
A family study was done of a pedigree obtained by screening for rhodopsin, peripherin/RDS, or rom-1 gene mutations in
We report a mutation (Y99C) in guanylate cyclase activator 1A (GUCA1A), the gene for guanylate cyclase activating protein (GCAP1), in a family with autosomal dominant cone dystrophy. Linkage analysis excluded all the known cone and cone-rod dystrophy loci, except the chromosome 6p21.1 region. This
The regulation of cGMP levels is central to the normal process of phototransduction in both cone and rod photoreceptor cells. Two of the proteins involved in this process are the enzyme, retinal guanylate cyclase (retGC), and its activating protein (GCAP) through which activity is regulated via
