The autosomal recessive inherited Krabbe disease (KD) is a devastating pediatric
lysosomal storage disorder affecting white matter of the brain. It is caused by
mutations in the gene coding for the lysosomal enzyme galactocerebrosidase. While
most patients present with symptoms within the first 6 months of life, others
present later in life throughout adulthood. The early infantile form of KD (EIKD)
is frequent in the Muslim Arab population in Israel, with a very high prevalence
of approximately 1/100 to 1/150 live births. The homozygous variant c.1582G?>?A
(p.D528N) was found to be responsible for EIKD in Palestinian Arab patients. KD
was reported in different Arab countries with much lower frequency. While most
Arab patients presented with EIKD, late infantile and late onset KD forms were
also reported. Most Arab patients presented with variable symptoms ranging from
EIKD to late onset KD, with variable clinical findings. Based on literature
studies, this review focuses on the clinical and molecular findings of KD
patients with Arab ancestry, and highlights the need for developing universal
genetic screening programs to overcome the under-reported status of KD prevalence
in Arabia. This is expected to improve the prognosis of the disease and promote
targeted molecular diagnostics to the Arab patients.
