Unraveling Hermansky-Pudlak syndrome type 7: a case report and comprehensive literature review on the identification of < em > DTNBP1 < /em > variants
CONCLUSION: This work highlights the genetic complexity of HPS-7 and emphasizes the importance of genetic testing in the diagnosis of this rare disorder. The identification of a rare pathogenic variant expands our understanding of HPS-7 genetics and suggests a possible founder effect in the Portuguese population.PMID:38097925 | DOI:10.1080/13816810.2023.2291670 (Source: Ophthalmic Genetics)

Schimmelpenning-Feuerstein-Mims syndrome with orbital choristoma and < em > KRAS < /em > mutation: a current review and novel case report
DISCUSSION: SFMS, a rare neurocutaneous disorder, results from postzygotic mosaic mutations in the RAS/MAPK pathway. Patients present with various systemic findings and ophthalmic manifestations occur in most cases. This is the first case description of a KRAS mutation identified in an orbital choristoma in SFMS. The disease is described under various names in the literature, and we propose that all syndromic cases with mosaic RAS mutations be reported under the eponym, SFMS.PMID:38097938 | DOI:10.1080/13816810.2023.2291664 (Source: Ophthalmic Genetics)

Case report: ocular manifestations of a gain-of-function mutation in < em > CLCN6 < /em > , a newly diagnosed disease
CONCLUSION: While Clcn6-/- mice have been found to have a mild neuronal lysosomal storage phenotype, the three reported children with a de novo c.1658A>G (p.Tyr553Cys) variant displayed significant developmental delay and neurodegeneration.PMID:38095064 | DOI:10.1080/13816810.2023.2291683 (Source: Ophthalmic Genetics)

Foveal hypoplasia in a Chinese adolescent with 48, XXYY syndrome
CONCLUSION: We described novel OCT and OCTA features of bilateral foveal hypoplasia and reduction of FAZ in a case of 48, XXYY syndrome based on detailed clinical observation and thorough genetic testing. This case expanded the current literature of this rare sex chromosome abnormality and suggest the importance of retinal examinations in 48, XXYY syndrome.PMID:38087495 | DOI:10.1080/13816810.2023.2291669 (Source: Ophthalmic Genetics)

Association of < em > GNB3 < /em > , < em > ACE < /em > polymorphisms with POAG and NTG
CONCLUSION: This study provides evidence of an association between the T allele of rs5443 and a reduced susceptibility NTG within the Russian population. These observations augment the comprehension of the genetic underpinnings of glaucoma and hold potential implications for the prospective development of targeted therapeutic interventions.PMID:37997634 | DOI:10.1080/13816810.2023.2283415 (Source: Ophthalmic Genetics)

Band-shaped keratopathy in < em > HNF4A < /em > -related Fanconi syndrome: a case report and review of the literature
CONCLUSIONS: Our case highlights the occurrence of BSK in an exceptionally rare manifestation of hereditary FS linked to HNF4A gene variant. The variant exists both in proband and asymptomatic mother. Therefore, the variable penetrance which is known to exist in HNF4A is acknowledged in this context. This report suggests the first documented instance establishing a plausible connection between BSK and HNF4A-associated FS, characterized by the variable penetrance attributed to the HNF4A gene.PMID:37997707 | DOI:10.1080/13816810.2023.2285310 (Source: Ophthalmic Genetics)
