High incidence of Meckel's syndrome in Gujarati Indians.

Five probable cases of Meckel's syndrome have been ascertained retrospectively through the Leicestershire Perinatal Mortality Survey for the years 1976 to 1982. All of these babies were born to Hindu parents originating from the Gujarat State in India, suggesting that Meckel's syndrome is particularly common among this ethnic group, with a gene frequency of approximately 0.028.
