Abnormal increase of the amino acid lysine in the circulating blood; associated with mental retardation, convulsions, anaemia, and asthenia; autosomal recessive inheritance.

hypermagnesaemia |
Excess magnesium. Persons with impaired kidney function should be especially careful about their magnesium intake because they can accumulate magnesium, a dangerous (and sometimes fatal) situation.
