ABSTRACT
A six-day-old girl, born to normal non-consanguineous parents presented with mask like facies with a small mouth giving a ‘whistling’ appearance. Other dysmorphic features include deep set eyes, broad nasal bridge, long philtrum and ‘H’ shaped cutaneous dimple on the chin. There was congenital windmill vane hand position and severe talipes equinovarus deformity. The above features are characteristic of Freeman-Sheldon syndrome also known as Whistling Face syndrome. Ultrasound scanning during 8th month of the pregnancy showed the fetus to have facial abnormality and bilateral clenched hand and talipes with extension contractures of knees. Provisional diagnosis of FSS was made which was confirmed after the birth. Thus all cases of Arthrogryposis during prenatal scan should be carefully looked for the facial abnormality in the fetus.

Alterations in tumour suppressor p53 gene are the most common defects seen in a variety of human cancers. In order to study the significance of the p53 gene in the genesis and development of human glioma from Indian patients, we checked 44 untreated primary gliomas for mutations in exons 5-9 of the p53 gene by PCR-SSCP and DNA sequencing. Sequencing analysis revealed six missense mutations. The incidence of p53 mutations was 13.6% (6 of 44). All the six mutations were found to be located in the central core domain of p53, which carries the sequence-specific DNA-binding domain. These results suggest a rather low incidence but a definite involvement of p53 mutations in the gliomas of Indian patients.
