Segmental narrowing of the aorta, also called middle aortic coarctation, can raise blood pressure sharply. Genetic testing may point to hereditary patterns.

Hemolytic anemia, acute renal failure and thrombocytopenia form the triad of aHUS, which is tied to faults in the complement system rather than to E. coli infection.

Weakness and wasting in the hands and feet can begin in adolescence or adulthood. A recurrent WARS mutation, affecting tryptophanyl-tRNA synthetase, is one cause.

Cognitive impairment without physical or developmental anomalies makes ADNSID hard to diagnose. Whole exome sequencing found a de novo ZBTB18 variant behind it.

Fluid seeping through a retinal tear lifts the retina and can cost sight permanently. In the autosomal dominant form, carriers can be monitored more closely.

Balance, coordination and speech decline as the cerebellum is affected in ARCA. Long-read sequencing detects repeat expansions that short-read methods can miss.

Leg stiffness and weakness, mental impairment and a thin corpus callosum define ARCSP, which a study in a Tunisian family traced to the SPG46 locus.
