Bainbridge-Ropers Syndrome (BRPS) is a genetic condition resulting from truncating variants in the ASXL3 gene. The clinical features include neurodevelopmental and language impairments, behavioral issues, hypotonia, feeding difficulties, and distinctive facial features. In this retrospective study, we analyzed 22 Spanish individuals with BRPS, aiming to perform a detailed clinical and molecular description and establish a genotype-phenotype correlation.

So far, mutations in the mitochondrial flavoprotein FDXR have been associated with a progressive neuropathic mitochondriopathy named FDXR-related mitochondriopathy (FRM), but cortisol insufficiency has not been documented. However, patients with FRM often experience worsening or demise following stress associated with infections.
