Diagnostic Challenges in Retinitis Pigmentosa: Genotypic Multiplicity and Phenotypic Variability
Open accessAbstract
Retinitis pigmentosa (RP) is a heterogeneous group of inherited retinal disorders. Diagnosis can be challenging as more than 40 genes are known to cause non-syndromic RP and phenotypic expression can differ significantly resulting in variations in disease severity, age of onset, rate of progression, and clinical findings. We describe the clinical manifestations of RP, the more commonly known causative gene mutations, and the genotypic-phenotypic correlation of RP. Keywords: Electroretinography, Optical Coherence Tomography, Electro-Oculography, heterogeneity, Visual Acuity, genetic testing, genotype-phenotype correlation, phenotypic variation, clinical manifestation, heterogeneity, Retinitis pigmentosa

The variety of characteristics seen in different diseases adds a layer of complexity to the diagnostic process.
“the variety of characteristics seen in different diseases adds a layer of complexity to the diagnostic process [129,130].”
From Toward Safer Diagnoses: A SEIPS-Based Narrative Review of Diagnostic Errors (2026) · cites this paper as [129]
The Introduction says that RP has a vast differential diagnosis and that its broad range of clinical severity makes diagnosis challenging. This supports the point for retinitis pigmentosa, but the cited paper does not establish the broader claim across different diseases generally. (LLM, conf=0.82)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
