Intragenic homozygous deletions in the Large gene are associated with a severe neuromuscular phenotype in the myodystrophy (myd) mouse. These mutations result in a virtual lack of glycosylation of alpha-dystroglycan. Compound heterozygous LARGE mutations have been reported in a single human patient, manifesting with mild congenital muscular dystrophy (CMD)(More)
The pattern of epilepsy and other convulsive disorders in 1,000 consecutive Saudi nationals is described. These disorders were common with a hospital frequency rate of 8 per 1,000. Men were more frequently affected than women and 60% of the patients were under 10 years old at the onset of their illness. The epilepsies were the commonest type (74%). Febrile(More)
We describe a girl with physical anomalies, accelerated skeletal maturation, failure to thrive, and respiratory difficulties consistent with a diagnosis of Marshall-Smith syndrome (MSS). Chromosome analysis showed an inverted duplication of chromosome 2 [46,XX,inv dup(2)(q37q32) de novo] identified by G banding and confirmed by FISH. Several cases of(More)
In this retrospective study from Saudi Arabia, which is a rich and sunny country, we report our experience with 34 adolescents (20 females, 10 males) with rickets. The commonest cause was vitamin D deficiency (58.8%) followed by rickets due to low calcium intake (11.8%) and genetic causes, including possible 25-hydroxylase deficiency (8.8%). The etiology of(More)
We report for the first time from the Arabian Gulf area 3 patients with arthrogryposis multiplex congenita, cholestasis and renal tubular dysfunction from a Saudi family with 2 other siblings and 3 cousins who possibly died with a similar clinical picture. We also document for the second time in literature other findings in this syndrome including cerebral(More)
BACKGROUND Methotrexate (MTX) embryopathy was described nearly 50 years ago, when this agent began to be used as a cancer treatment and abortifacient. In this report we describe a case with typical features of MTX syndrome together with new features to expand the phenotype. CASE A 29-year-old woman decided to terminate her unwanted pregnancy because of(More)
A four-year-old deaf girl with a history of convulsions developed polymorphous ventricular tachycardia during induction of anaesthesia. The arrhythmia reverted to sinus rhythm spontaneously. Post-anaesthetic ECG showed marked prolongation of the QTc interval (570-690 msec). Deafness and prolonged QTc interval in association with microcytic-hypochromic(More)
BACKGROUND Although intravenous immunoglobulin G (IVIG) therapy has been reported in hyperbilirubinemia of Rh hemolytic disease, its use in ABO hemolytic disease has been reported in only a few studies. In our institute we have observed that almost 30% of babies with hyperbilirubinemia due to ABO hemolytic disease required exchange transfusion. OBJECTIVE(More)
