| A rare chromosomal anomaly syndrome with a highly variable phenotype that may range from normal to patients with profound intellectual disability, developmental delay, learning disability (especially speech) and mild dysmorphism (including micro/macrocephaly, prominent forehead, low-set and posteriorly rotated ears, hypertelorism, high nasal bridge, prominent philtrum, retro/micrognathia). Mild hypotonia and autistic-like mannerisms (for example hand opening and closing, head banging) may also be associated. Other anomalies, such as cutis laxa, hearing loss, syndactyly, digital hypoplasia and talipes equinovarus have also been reported. |
