RT Journal Article SR Electronic T1 An Ashkenazi Jewish woman presenting with favism JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 317 OP 319 DO 10.1136/jcp.2004.017426 VO 58 IS 3 A1 F Lim A1 T Vulliamy A1 S H Abdalla YR 2005 UL http://jcp.bmj.com/content/58/3/317.abstract AB The case of a 44 year old Ashkenazi Jewish woman of Russian origin who presented with a typical clinical and haematological picture of favism is reported. There was initial difficulty in confirming glucose-6-phosphate dehydrogenase (G6PD) deficiency because the enzyme concentrations were normal at presentation, but later fell to a concentration compatible with heterozygosity for the Mediterranean type of G6PD deficiency. The diagnosis was also later confirmed by gene analysis. The reasons for the difficulties in the initial confirmation of the diagnosis and the normal G6PD enzyme activity at presentation are discussed.
