Zornitza Stark gene: IMPG1 was added gene: IMPG1 was added to Retinitis pigmentosa_Autosomal Recessive/X-linked. Sources: Literature Mode of inheritance for gene: IMPG1 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: IMPG1 were set to 32817297 Phenotypes for gene: IMPG1 were set to Retinitis pigmentosa, MONDO:0019200 Review for gene: IMPG1 was set to AMBER Added comment: Variants in this gene are classically associated with macular dystrophy. However note recent paper by Olivier et al. 2021 (PMID: 32817297) who identified seven variants in IMPG1 (including five novel) in 11 families with VMD or retinitis pigmentosa (RP). 4 families were diagnosed with autosomal dominant RP, 2 families had autosomal recessive RP, while 5 families developed VMD in association with heterozygous IMPG1 variants. Notably, inter- and intrafamilial phenotypic variation was evident with some individuals presenting RP while others had VMD, despite harbouring the same IMPG1 variant. Knockdown of Impg1 in medaka fish resulted in a phenotype consistent with that observed in human patients, including a decreased length of rod and cone photoreceptor outer segments.
