Ben-Gurion University researchers found that 1 in 37 Moroccan Jews carries 1 of the 2 mutations of the gene PCCA 2, that causes severe mental retardation & epilepsy in infants.
Researchers from Ben-Gurion University in Be’er Sheva have identified the genetic mutation behind a hereditary disease that causes epilepsy and severe developmental delays among Moroccan Jews.

In light of the high carrier rate for the disorder, screening for the disease will likely be added to the routine genetic testing offered to couples of Moroccan Jewish heritage. – Photo: Dreamstime
The disease, which the researchers are calling Progressive cerebello-cerebral Atrophy, type 2, is caused by mutations in the VPS53 gene.
