This article reports two cases of RP with pathogenic variants in AGBL5, providing further evidence of its role as a cause of autosomal recessive RP.
Background: Retinitis pigmentosa (RP) is the leading cause of heritable retinal visual impairment. Clinically, it is characterized by a variable onset of progressive night blindness and visual field constriction. RP is characterized by wide genetic heterogeneity with a broad range of potential genes involved in the genesis of this disease. Very few cases have been reported of RP due to pathogenic variants in AGBL5.Materials and methods: We report two patients with RP and bilallelic pathogenic variants in AGBL5.Results: Genetic sequencing showed one homozygous AGBL5 missense variant in one patient and a homozygous nonsense variant in the other. These patients presented with progressive peripheral vision loss and nyctalopia. Their RP phenotypes were similar to previous reports in literature.Conclusion: These two cases provide further evidence regarding the relationship of pathogenic variants in AGBL5 as a cause of autosomal recessive RP.
