Prevalent MLC1 mutation causing autosomal recessive megalencephalic leukoencephalopathy in consanguineous Palestinian families

In this study, we identified a recurrent MLC1 variant (c.423 + 1G > A) as the cause of MLC among a group of Palestinian patients originating from a particular region of the country. Cost-effective studies should be performed to evaluate the implementation of carrier screening in adults originating from this region. Our findings have the potential to contribute to improved genetic diagnosis and carrier testing for individuals within this population and the wider community.
