Cancer stem cells (CSCs) have historically been defined as slow cycling elements that are able to differentiate into mature cells but without dedifferentiation in the opposite direction. Thanks to advances in genomic and non-genomic technologies, the CSC theory has more recently been reconsidered in a dynamic manner according to a “phenotype switching” plastic model.

NDUFB11, a component of mitochondrial complex I, is a relatively small integral membrane protein, belonging to the 'supernumerary' group of subunits, but proved to be absolutely essential for the assembly of an active complex I. Mutations in in the X-linked nuclear encoded NDUFB11 gene have recently been discovered in association with two distinct phenotypes, i.e. microphthalmia with linear skin defects and histiocytoid cardiomyopathy.
