A mentally retarded 7-year-old male child presented with inattention and hyperactivity which was initially diagnosed as attention deficit hyperactivity disorder (ADHD). However, a careful evaluation of symptomatology along with clues provided by specific features of facial dysmorphism in this case along with genetic testing clinched the diagnosis of Smith-Magneis syndrome the behavioural phenot...

Two girls with mosaicism for an extra chromosome 9 are reported. Clinical findings included growth and mental retardation, facial dysmorphism, delayed ossification, single flexion crease, gastro-oesophageal reflux in one girl, and ventricular and atrial septal defects in the other patient. These findings are compared to the other previously reported cases of trisomy 9 mosaicism.

We present a 15 year old boy who was born out of a non consanguineous marriage, and presented with bilateral cryptorchidism, mental retardation, facial dysmorphism, hypergonadotrophic hypogonadism with failure of anatomical and biochemical localisation of testes. Karyotype analysis showed 46 XY with inverted duplication on chromosome 5q22-31.

Pituitary duplication is a rare malformation commonly associated with other major neural/craniofacial anomalies, easily shown by magnetic resonance imaging. The authors describe two girls with duplication of the pituitary gland and thickening of the hypothalamus, facial dysmorphism and precocious pubertal development. The pathogenesis of pituitary duplication and its relationship with precociou...

Two unrelated patients with monosomy 13q32.3----qter are reported. Comparison with six similar cases previously published indicates that the craniofacial dysmorphism of the 13qter monosomy syndrome is related to band 13q34, the thumb hypoplasia to band 13q32, and an apparently different phenotype to band 13q33. Coagulation deficiency appears to be non-specific in monosomy 13qter.

Prolidase deficiency is a rare autosomal recessive disorder characterized by recurrent and nonhealing skin ulcers along with facial dysmorphism and mental retardation. We report a 13-year-old girl who has clinical manifestation of Proliodase deficiency. It is a very rare disorder and no such case has been reported so far from Pakistan.

Late infantile GM1 gangliosidosis is an extremely rare metabolic disorder with clinical features of seizure and progressive motor and mental retardation without facial dysmorphism or visceral organomegaly. We report the CT and MR imaging findings in one infant, which included abnormalities of the cerebral cortex, white matter, and deep nuclei.
