The Lowe syndrome, or oculocerebrorenal syndrome, is a rare X-linked recessive hereditary disease which typically involves three major systems including ocular defects (congenital cataracts, glaucoma, searching nystagmus), central nervous system defects (generalized hypotonia with decreased or absent deep tendon reflex and severe mental retardation), and renal dysfunction (progressive renal tubular dysfunction with acidosis and hyperaminoaciduria). Less than 200 cases have been reported in the English literatures since 1952. This article presents the first case of Lowe syndrome in Taiwan. Patient was a newborn who was born with congenital cataracts, glaucoma, generalized hypotonia with areflexia. In following laboratory studies showed early manifestations of renal tubular dysfunction with metabolic acidosis, proteinuria, glycosuria, phosphaturia and generalized hyperaminoaciduria (19 types). CT of brain showed an arachnoid cyst about 4.5 x 5 cm in size below the cerebellar tentorium. Large amount of copper, about 20-30 times above normal range, was detected in the urine. To our knowledge, Lowe syndrome associated with hypercupriuria and arachnoid cyst has not been reported in the past. Whether hypercupriuria is a part of the entity of this disease or prodromal stage of Wilson's disease is obscure. Further investigation and long-term observation are necessary to draw any conclusion.

The combination of multiple exostoses (EXT) and enlarged parietal foramina (foramina parietalia permagna, FPP) represent the main features of the proximal 11p deletion syndrome (P11pDS), a contiguous gene syndrome (MIM 601224) caused by an interstitial deletion on the short arm of chromosome 11. Here we present clinical aspects of two new P11pDS patients and the clinical follow-up of one patient reported in the original paper describing this syndrome. Recognised clinical signs include EXT, FPP, mental retardation, facial asymmetry, asymmetric calcification of coronary sutures, defective vision (severe myopia, nystagmus, strabismus), skeletal anomalies (small hands and feet, tapering fingers), heart defect, and anal stenosis. In addition fluorescence in situ hybridisation and molecular analysis were performed to gain further insight in potential candidate genes involved in P11pDS.

Aniridia, Wilms tumor, genitourinary abnormalities, growth and mental retardation are the cardinal features of the WAGR 11p13 deletion syndrome. The Potocki-Schaffer syndrome or proximal 11p deletion syndrome (previously DEFECT11 syndrome) is a contiguous gene syndrome associated with deletions in 11p11.2, principal features of which are multiple exostoses and enlarged parietal foramina. Mental handicap, facial dysmorphism and craniosynostosis may also be associated. We report a patient with combined WAGR and Potocki-Shaffer syndromes, and obesity. She presented with aniridia, cataract, nystagmus, corneal ulcers and bilateral congenital ptosis. A left nephroblastoma was detected at 15 months. Other features included moderate developmental delay, growth deficiency, facial dysmorphism, multiple exostoses and cranial lacunae. High-resolution and molecular cytogenetics confirmed a del(11)(p11.2p14.1) deletion with a proximal breakpoint between the cosmid DO8153 and the BAC RP11-104M24 to a distal breakpoint between cosmids CO8160 (D11S151) and F1238 (D11S1446). The deletion therefore includes EXT2, ALX4, WT1 and PAX6. This case appears to be the second patient reported with this combined deletion syndrome and confirms the association of obesity in the WAGR spectrum, a feature previously reported in four cases, and for which the acronym WAGRO has been suggested. Molecular and follow-up data on the original WAGRO case are briefly presented.
