  • Lowe syndrome, also known as oculocerebrorenal syndrome, is a rare genetic disorder involving eyes, kidney and nervous system, and occurs predominantly in mostly males. The patients with Lowe syndrome are characterized with prominent forehead, thin and sparse hair, protruding ears, congenital cataracts, glaucoma, mental retardation, stunted growth, hypotonia, decrease in muscle mass and tendon reflexes, renal tubular dysfunction, and metabolic bone disease. A 6-year-old boy with Lowe syndrome was admitted to our clinic, with multiple caries and a chief complaint of intermittent pain on the left mandibular molar area. Because of difficulty in management of behavior and his medical problem, general anesthesia was performed for dental care. No specific complication was noticed during dental treatment procedure under general anesthesia and also during periodic recall-checks. General anesthesia itself, however, could be a potentially life-threatening procedure due to patient's biomedical problems. When a dental procedure under general anesthesia is to be required in patient with Lowe syndrome, it may be advisable being teamed with physicians, and general anesthesia duration should be as short as possible.

  • Lowe syndrome, also known as oculocerebrorenal syndrome, is a rare genetic disorder involving eyes, kidney, brain and musculoskeletal system, and occurs predominantly in males. The patient with Lowe syndrome is characterized with congenital cataracts, glaucoma, prominent forehead, thin and sparse hair, mental and growth retardation, muscular hypotonia, renal dysfunction, and metabolic bone disease. We have experienced a 10-year-old boy with Lowe syndrome who had poor oral hygiene and trouble for teeth brushing. To manage his behavior and systemic metabolic disorder, sedation was performed during dental care. Excessive calculus formation in this patient is caused by both medication and lack of ability to maintain oral hygiene. The dental management of those patients has to be focused on prevention due to difficulties in dental treatment and dangers of general anesthesia for the Lowe syndrome.

  • Purpose: Lowe syndrome is a rare, X-linked recessive disorder caused by mutations in the OCRL gene. It involves multiple anatomic systems, particularly the eyes, central nervous system, and kidneys, and leads to profound growth failure and global developmental delay. This study evaluated the clinical and genetic characteristics of Korean patients with Lowe syndrome. Methods: The clinical findings and results of genetic studies were reviewed for 12 male patients diagnosed with Lowe syndrome at a single medical institution. Results: The mean age of the patients at presentation was 2.2 months (range, 0-4 months), although the diagnosis was delayed by a mean of 2.8 years (range, 0-9.7 years). The mean follow-up period was 9.0 years (range, 0.6-16.7 years). Nine mutations in OCRL were identified in 11 patients (92%), with three novel mutations. The main presentation was congenital cataract in both eyes necessitating early cataract removal in the 11 patients with impaired visual acuity. Profound short stature and developmental delay were observed in all patients, and seizures occurred in 50% of the patients. All patients suffered from proximal renal tubular dysfunction, and one patient developed chronic renal failure. Other manifestations included pathologic fracture (50%), cutaneous cysts (42%), and cryptorchidism (42%). However, there was no bleeding tendency, and none of the patients died during the study period. Conclusion: This study describes the clinical and genetic characteristics of Korean patients with Lowe syndrome. The observations are helpful for understanding the natural courses of Lowe syndrome and for appropriate genetic counseling.
