Monarch Disease Ontology id MONDO_0015712 (non-distal trisomy 10q) is a rare chromosomal anomaly syndrome, resulting from the partial duplication of the long arm of chromosome 10, characterized by mild to moderate developmental delay, postnatal growth retardation, central hypotonia, craniofacial dysmorphism (incl. microcephaly, prominent forehead, flat, thick ear helices, deep-set, small eyes, epicanthus, upturned nose, bow-shaped mouth, highly arched palate, micrognathia), ocular anomalies (e.g. iris coloboma, retinal dysplasia, strabismus), long, slender limbs and skeletal and digital anomalies (scoliosis, poly/syndactyly). Additional features reported include cardiac defects (e.g. septal ventricular defect), anal atresia, and cryptorchidism. Also known as: non-distal duplication 10q, non-distal trisomy type 10q, non-telomeric trisomy 10q.
