Facial anomalies include ocular hypertelorism, small beaked nose, proptosis, exophthalmos, hypoplastic maxilla and mandibular prognathism. Caused by mutations of the fibroblast growth factor receptor FGFR2 (10q25.3-q26) with 80% being located to the immunoglobulin (Ig)-like domain III (IgIII domain) of the extracellular region and an additional 20% of mutations being located in the IgI-IgII domains, transmembrane and tyrosine kinase regions. The disease is transmitted in an autosomal dominant manner with variable penetrance. |

| A sex chromosome anomaly caused by the presence of two extra X chromosomes in females (48,XXXX instead of 46,XX). This disorder is associated with delayed speech, learning difficulties, developmental delay and facial dysmorphism. Although disease severity is variable, the learning difficulties and developmental delay are generally mild to moderate. Commonly associated facial features include hypertelorism, upslanting palpebral fissures, epicanthal folds and a flat nasal bridge. Other anomalies may include dental abnormalities, hypotonia and joint laxity, radioulnar synostosis, heart defects, hip dysplasia, and ovarian dysfunction. An increased susceptibility to infections during childhood has also been reported. |

| A rare X-linked genomic disorder associated with interstitial chromosomal duplications at Xq28 encompassing the MECP2 gene. In males the disease has characteristics of infantile onset hypotonia, severe global developmental delay, intellectual disability, progressive spasticity, seizures, gastrointestinal symptoms and recurrent respiratory infections. In females, the phenotype is more variable. The syndrome is due to Xq28 duplications (< 4 Mb) involving the dosage-sensitive gene MECP2. The pattern of inheritance is X-linked. The recurrence risk is significant if the duplication encompassing the MECP2 gene is inherited from the mother, but very low if the duplication is de novo. There is full disease penetrance in males and variable penetrance in females due to the level and type of X-inactivation. |
