Haemoglobins J in Canada.
A search has been conducted in Canada on 222,000 blood samples, for haemoglobin variants detectable electrophoretically. A pattern of Hbs A h was found in 41, and of these, 23 have been identified as J Baltimore (in 18), J Toronto (in 1), J. Broussais (in 3) and St. Claude (in 1). 12 instances of J Baltimore and one of J Toronto came from English Canadians, while the remainder came from French Canadians. Of those not identified, five were considered to be J-alpha and 13 J-beta variants. The known distribution and incidence of J Baltimore, and of the Hbs J that have been found in the indigenous populations of the United Kingdom and of France, are reviewed.
