Outline of Final Research Achievements

We established genotype-phenotype correlation of Stickler syndrome. We found novel retinal findings in patients with Stickler syndrome who had mutations in the COL2A1 gene. Foveal hypoplasia is a consistent feature whereas vision decrease was not associated. Electroretinogram revealed that Stickler syndrome showed age-related photoreceptor degeneration. Ultra-wide field fundus autofluorescence indicated that the examination was useful to detect earlier and characteristic changes of altered autofluorescence along funduscopic paravascular retinal degeneration. These findings offer a correct diagnosis of Stickler syndrome.

Academic Significance and Societal Importance of the Research Achievements

小児の網膜剥離は難治性疾患であり、発見の遅れにより失明し、社会的に大きな損失を来す要因となる。Stickler症候群は遺伝性の小児網膜剥離を来す代表的疾患であるが、その臨床像は確立されていない。我々はこれまで明らかでなかったStickler症候群の臨床像として、黄斑低形成、網膜電図の経年的減弱、眼底自発蛍光異常が見られることを見出し、その診断的意義を明らかにした。本研究によりStickler症候群の早期からの正確な臨床診断を行うことが可能となった。さらにStickler症候群に占めるCOL2A1遺伝子変異の頻度が明らかとなり、遺伝子診断の基礎となる重要な知見を得ることができた。
