Abstract

En 中文
• 0c.1535G > A (p.R512Q) and c.1753C > T (p.R585W) in SDHA impair CII activity and assembly • Patient fibroblasts show reduced complex I activity and CI-containing supercomplexes. • Patient fibroblasts maintain basal respiration but exhibit reduced spare capacity. • Functional studies support pathogenicity and variant reclassification.
