Letter to the Editor

Dear Editor-in-Chief,

Schimke immuno-osseous dysplasia (SIOD) is an uncommon autosomal-recessive multisystem disease caused by mutations in SMARCAL1, a gene encoding a chromatin-remodeling enzyme that stabilizes stalled replication forks and prevents replication-associated DNA damage (OMIM 242900) [1]. The disease is characterized by spondyloepiphyseal dysplasia, nephropathy, immunodeficiency, and growth failure. Several neurologic manifestations have been described, including microcephaly, intellectual disability, seizures, stroke, transient neurological attack, and migraine-like headache [1].

Cerebrovascular pathology in SIOD may result from several predisposing factors, such as renal disease and immune dysfunction, leading to occlusive disease and early atherosclerosis [2]. Recently, Morimoto et al. demonstrated that vascular complications may also arise from impaired vascular elastogenesis, showing decreased elastin expression in vascular tissues, leading to disorganized internal...
