Laurence-moon-biedl Syndrome.

Case Report A boy aged 10 years was brought to the children's out-patient department of the Patna Medical College Hospital on account of his abnormal flabbiness and mental deficiency. In addition he had not been able to see very well for some time, particularly at night. He was the third child of his parents, who were healthy and not consanguineous. The family, traced to four generations on the father's side and three on the mother's, was essentially normal with no history of consanguinity. Two children, a brother and sister, had died in infancy, and as far as could be ascertained showed no ocular or general manifestations of the syndrome. The patient's surviving sister was 12 years old and normal in all respects. His younger brother was aged 4 years, was quite intelligent, but had supernumerary fingers-seven on the right hand, and six toes on both feet. His ocular and general examinations revealed no other abnormality.
