Unstable insertion of the 5-prime flanking region of the cystatin B gene is the most common mutation in progressive myoclonus epilepsy type 1, EPM1.

Recurrent expansion of this repeat prigressive canine Epm2b makes LD particularly common in dogs, but this mechanism does not occur in human cases with LD Lohi et al. No clear disease entity was associated with these jerks Friedreich, Swedish Society for race hygiene; No patient is reported to have, or probably exists with, a total loss of EPM1.

Genton P, Guerrini R. It is probably safe to say that we have now identified most PME genes, but it is equally safe to expect that many others remain to be found.

For example, human ULD is a disease which is not due to the complete absence of the responsible gene EPM1but to drastic downregulation of the gene’s expression caused by expansion of a dodecamer repeat sequence. Cerebral degeneration with symmetrical changes in the maculae in two progrssive of a family.
