Comment on list classification: There is sufficient evidence for this gene to be promoted to GREEN at the next major review. These include at least four unrelated cases with retinal disorders in literature and additional two cases reported by Siying Lin (Moorfields Eye Hospital).Created: 5 Apr 2023, 1:54 p.m. | Last Modified: 5 Apr 2023, 1:55 p.m.

PMID:31718697 reported that patients from three unrelated families with Mucopolysaccharidosis type III (MPS-III) presented with retinal dystrophy and another unrelated patient was presented with retinitis pigmentosa. They were identified with compound heterozygous variants in SGSH gene.
Siying Lin (Moorfields Eye Hospital) also reviewed about two additional cases of retinal dystrophy identified with biallelic SGSH variants in their patient cohort.
In addition, MPS-IIIA mice exhibited a progressive retinal dystrophy characterized by significant alterations in visual function (PMID:32195255).
Although SGSH gene has already been associated with MPS-IIIA in both OMIM and Gene2Phenotype, retinal phenotypes have not yet been included in these records.Created: 5 Apr 2023, 1:49 p.m. | Last Modified: 5 Apr 2023, 1:51 p.m.

Reports of late onset retinal dystrophy with mild systemic involvement (attenuated MPS phenotype) associated with biallelic genotypes which include likely hypomorphic alleles. Also two individuals identified in our clinical cohort with retinal dystrophy associated with biallelic SGSH variants.
