Autosomal Dominant Retinitis Pigmentosa

Area of Science:

• Ophthalmology
• Genetics
• Medical Science

Background:

• Non-syndromic retinitis pigmentosa (RP) is a group of inherited retinal diseases.
• Over 70 genes are implicated, with more than 3000 known mutations.
• RP exhibits diverse inheritance patterns, including autosomal dominant (AD), autosomal recessive (AR), and X-linked.

Purpose of the Study:

• To summarize the genetic landscape of non-syndromic retinitis pigmentosa.
• To detail the prevalence of different inheritance patterns in RP.
• To highlight the genetic heterogeneity underlying RP.

Main Methods:

• Literature review of genetic causes of non-syndromic RP.
• Analysis of gene mutation databases.
• Compilation of prevalence data for different RP inheritance forms.

Main Results:

• Identification of over 70 causative genes and >3000 mutations for non-syndromic RP.
• Autosomal dominant RP accounts for 15-25% of cases.
• Autosomal recessive RP (5-20%), X-linked RP (5-15%), and simplex RP (40-50%) represent other major forms.

Conclusions:

• Non-syndromic RP is genetically complex with numerous causative genes.
• The simplex form of RP is the most prevalent.
• Understanding genetic heterogeneity is crucial for RP diagnosis and potential therapies.
