- PMID: 22579565 severe developmental delay, congenital microcephaly, intractable epilepsy, and renal anomalies, as well as a congenital choledochal cyst which has not been previously reported in other patients with this cytogenetic defect

- PMID: 16963482 idiopathic intellectual disability including moderate to severe intellectual disability, autism/autistic features, microcephaly, structural brain anomalies including cortical dysplasia/pachygyria, renal anomalies (multicystic kidney, hydronephrosis), digital camptodactyly, visual impairment, strabismus, neuromotor deficits, communication and attention impairments, and a distinctive pattern of craniofacial features. Dysmorphic craniofacial features include progressive microcephaly, flat occiput, widened inner canthal distance, small palpebral fissures, ptosis, long and straight eyelashes, broad and high nasal root extending to a widened, prominent nasal tip with elongated, smooth philtrum, rounding of the upper vermillion border and everted lower lips. PMID: 18245392 A 32-year-old, mentally retarded male was referred to our centre for further clinical genetic analysis. He was born to non-consanguineous parents after 42 weeks gestation with a birth weight of 3500 g. He had a healthy older brother. In the neonatal period he was hypotonic and at 8 weeks of age he underwent surgery because of an inguinal hernia with removal of an atrophic right testis. His motor development was severely delayed with sitting at 3.5 years and walking at 5 years of age. Speech was poorly developed, characterised by the usage of only a few words. During infancy an optic nerve hypoplasia was diagnosed, and during childhood he frequently suffered from luxations of the patellae, which required surgery. At the age of 32 years his height is 163 cm (_3 SDS) and head circumference 52.5 cm (_2.5 SDS). He has a narrow receding forehead, widened inner canthal distance of 3.5 cm (90th centile), normal outer canthal distance of 8.5 cm (25th centile), telecanthus, short and down slanting palpebral fissures, epicanthal folds, ptosis, long, straight eyelashes, high nasal bridge, low set large ears, flat philtrum, small mouth with high, narrow palate and retrognathia. The thorax is broad with increased internipple distance and slight gynaecomastia. A recent renal ultrasound revealed multiple cysts in the left, dystrophic kidney and two uncomplicated cysts in the enlarged, right kidney. The patient has a normally sized phallus with absent right testis and small left testis. His hands show a simian crease right and tapering fingers with broad proximal interphalangeal joints. He shows sandal gaps on both flat feet with clinodactyly of the fourth and fifth toes (and more)
