NDUFB11

Chr XX-linkedXLD

NADH:ubiquinone oxidoreductase subunit B11

Also known as: CI-ESSS, ESSS, MC1DN30, NP17.3, Np15, P17.3

The NDUFB11 protein is an accessory subunit of mitochondrial complex I (NADH dehydrogenase), which transfers electrons from NADH to ubiquinone in the respiratory chain. Mutations cause X-linked mitochondrial complex I deficiency and linear skin defects with multiple congenital anomalies 3, affecting both metabolic and developmental processes. This gene shows high constraint against loss-of-function variants (LOEUF 0.556), indicating that such mutations are likely to have significant clinical consequences.
