Al‐Raqad syndrome (ARS) is a rare autosomal recessive congenital disorder, associated mainly with developmental delay, and intellectual disability. This syndrome is caused by mutations in DCPS, encoding scavenger mRNA decapping enzyme, which plays a role in the 3‐prime‐end mRNA decay pathway. Whole‐exome sequencing was performed on an offspring of a consanguineous family presenting with developmental delay, intellectual disability, growth retardation, mild craniofacial abnormalities, cerebral and cerebellar atrophy, and white matter diffuse hypomyelination pattern. A novel biallelic missense variant, c.918G>C p. (Glu306Asp), in the DCPS gene was identified which was confirmed by sanger sequencing and segregation analysis subsequently. Few cases of ARS have been described up to now, and this study represents a 7‐years‐old boy presenting with central and peripheral nervous system impaired myelination in addition to ocular and dental manifestation, therefore outstretch both neuroimaging and clinical findings of this ultra‐rare syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
