Ring chromosome 5 syndrome is a rare chromosomal anomaly syndrome, with high phenotypic variability, principally characterized by a neonatal mewing cry, severe developmental delay and intellectual disability, short stature, hypotonia, dysmorphic features (incl. microcephaly, facial asymmetry, hypertelorism, epicanthal folds, abnormal ears, micro/retrognathia), congenital cardiac anomalies (such as atrial and ventricular septal defect, tricuspid insufficiency, hypoplastic aorta) and skeletal abnormalities (e.g. hypoplastic thumbs, anomalous ulna/radius, dysplastic metacarpals and phalanges). [from ORDO]

An extragonadal non-seminomatous malignant germ cell tumor that arises from the mediastinum. It is characterized by the presence of small pale cells with small amount of cytoplasm and round to oval nuclei with small nucleoli forming a variety of patterns, including microcystic, macrocystic, pseudopapillary, myxomatous, hepatoid, polyvesicular vitelline, and solid. It manifests with respiratory distress, thoracic pain, fever, and superior vena cava syndrome. [from NCI]

A rare chromosomal anomaly syndrome with a highly variable phenotype. Principle characteristics are prenatal/postnatal growth failure, intellectual disability, developmental delay, craniofacial dysmorphism (including microcephaly, microphthalmia, epicanthus, low-set and malformed ears, broad and flat nasal bridge, full lips, micrognathia), central nervous system anomalies (for example hydrocephalus, cortical atrophy, ventriculomegaly), short neck, and delayed bone age. Cardiac defects, limb anomalies, hip joint malformations and seizures have also been reported. [from SNOMEDCT_US]

An autosomal anomaly with characteristics of variable clinical features, most commonly including significant intrauterine and postnatal growth retardation, developmental delay, intellectual disability, microcephaly, and dysmorphic facial features. Some less frequent features are cleft lip and/or cleft palate, congenital cardiovascular, gastrointestinal and genitourinary system anomalies. [from SNOMEDCT_US]
