Abstract summary 

gene (alpha-thalassemia mental retardation X-linked) encodes for a chromatin remodeler and regular transcription protein, part of the SNF2 family of chromatin remodeling proteins. Mutations in this gene have been associated with severe syndromes, including intellectual disability, typical facial dysmorphia, urogenital anomalies, and atypical alpha thalassemia. In this report, we present a 7-year-old Moroccan boy with severe intellectual disability, autistic features, typical facial dysmorphia, bilateral cryptorchidism, and scoliosis. Whole exome sequencing identified a missense variant of uncertain significance in the gene (NM_000489.3: c.745G>A). In silico tools strongly predict the pathogenicity of this variant. Moreover, this variant occurs in a highly conserved domain, potentially affecting the function of the encoded protein, and the glycine at position 249 is well conserved across different species. Further studies are needed to confirm the pathogenicity of this novel variant to establish adequate genetic counseling.
