<div class="spaceAbove">Macrocephaly refers to an abnormally enlarged head inclusive of the scalp, cranial bones, and intracranial contents. Macrocephaly may be due to megalencephaly (true enlargement of the brain parenchyma), and the 2 terms are often used interchangeably in the genetic literature (reviews by Olney, 2007 and Williams et al., 2008). Autosomal recessive macrocephaly/megalencephaly syndrome is characterized by an enlarged cranium apparent at birth or in early childhood. Affected individuals have intellectual disability and may have dysmorphic facial features resulting from the macrocephaly (summary by Alfaiz et al., 2014).</div>

<div class="spaceAbove">Mega-corpus-callosum syndrome with cerebellar hypoplasia and cortical malformations (MCCCHCM) is an autosomal dominant neurodevelopmental disorder characterized by global developmental delay, impaired intellectual development, and characteristic brain abnormalities on brain imaging. Affected individuals have enlargement of the corpus callosum, enlarged ventricles, and cerebellar and brainstem hypoplasia. Other features may include lack of speech development, gait instability, and seizures. Some patients with MAST1 mutations may have impaired intellectual development and/or autism spectrum disorder without significant findings on brain imaging (summary by Tripathy et al., 2018).</div>

<div class="spaceAbove">Intellectual developmental disorder with speech delay, autism, and dysmorphic facies (IDDSADF) is a developmental disorder with the most highly consistent features of hypotonia, relatively small stature, developmental delay, behavioral problems, and impaired intellectual development. Variable dysmorphic facial features are present, without a consistent pattern. A predisposition to moyamoya angiopathy has been observed (Martin et al., 2019, Pinard et al., 2020).</div>
