A Case Report of Lowe Syndrome Diagnosed By Linkage Analysis

INTRODUCTION Lowe oculocerebro nephritic syndrome is a rare X-linked unhinge characterized by major deviateities of the lens, channeliseland and kidneys. It leads to the clinical triad of cataract formation during earlyish infancy, mental retardant and a broad range of renal abnormalities, including incomplete hydrogen carbonate resumption, renal tubular acidosis and end-stage kidney unsoundness (Lowe, Terrey, MacLachan, 1952, 83:164-84.)[1, 2]. The OCRL1 gene is get a line on chromosome Xq25-26(Lowe, Terrey, MacLachan, 1952, 83:164-84.)1 .Over 70 mutations have been identified. ( Charnas & vitamin A; Gahl, 1990; 38:75-107.)2 The OCRL gene encodes phosphatidylinositol 4, 5-biphospsphate 5-phosphatase (ocrl1p) is present in the Golgi complex, and reduced enzyme activity results in increased enzyme substrate and abnormal distribution of acting-binding proteins that may hit abnormal cell migration and differentiation.( Suchy & Nussbaum, 2002;71:1420-1427)4 CLINICAL REPORT This boy was the chip child of non-consanguineous healthy parents and had a birth weight of 2.9 kg at 40 weeks of gestation. He had generalized hypotonia and subjective cataracts afterward birth. Cranial ultrasonography showed features of generalized brain atrophy. Chromosome digest showed a normal 46,XY phallic karyotype and the TORCH screen was negative. nephritic and abdominal ultrasound findings were unremarkable. His psychomotor development was severe delay, with school term unsupported at 14 months, independent ambulation at 2 years and speaking his prime(prenominal) words at 2 years.

He was diagnosed as Lowe syndrome until age 4 years 10 months when he developed metabolic acidosis after lower airway infection. On examination, his height, weight and occipital frontage circumference below the one-fifth percentile for age. The face was trilateral in appearance; the principal sum was dolichocephalic with frontal bossing; hairline was receded anteriorly. The eye were deeply set. The ears were large, protruding, but unremarkably placed. The palate was highly arched. The philtrum was spectacular and elongated; the upper oral examination fissure was thin.
