We employed the rd10 mouse model (Pde6b <sup>rd10</sup> mutation) of retinitis pigmentosa (RP) to examine the involvement of BET proteins in retinal neurodegeneration.
THE FAMILY WAS FOUND TO SEGREGATE NOVEL MUTATIONS OF TWO DIFFERENT GENES: myosin VIIA (MYO7A), which causes type 1 Usher syndrome, and phosphodiesterase 6B, cyclic guanosine monophosphate-specific, rod, beta (PDE6B), which causes nonsyndromic RP.
Mutations in PDE6A and the PDE6B genes lead to autosomal recessive (ar) forms of retinitis pigmentosa (RP) in human and to the homologous disease in dogs, designated generalised progressive retinal atrophy (gPRA).

In previous efforts to identify the erd locus, canine homologs of genes causally associated with RP in humans, such as opsin (RHO), the beta-subunit gene for cyclic GMP phosphodiesterase (PDE6B), and RDS/peripherin, were excluded.
In previous efforts to identify the genetic locus for prcd, the canine homologs for many of the genes causally associated with RP in humans, such as RHO, PDE6B, and RDS/peripherin, have been excluded.
Using the PCR-SSCP method, sequencing analysis, and restriction endonuclease digestion assay, we analyzed the PDEB gene in 17 Japanese families with non-dominant retinitis pigmentosa.
