Editor's note: The pace at which mutations are being found has become so rapid that the publication of up-to-date tabulations has become impossible using conventional means. For example, the last comprehensive publication of glucose-6-phosphate dehydrogenase variants (reference 2 in the present paper) was submitted for publication on June 1994 and published in December of 1994. Since its publication 30 additional variants have been discovered and many that were unpublished in the earlier tabulation have now appeared in print Since papers are published in this journal within less than two weeks of receipt, reprints are available in 2 weeks, and the printed version is on library shelves within an average of 3 months, it provides an ideal medium for publication in such a rapidly moving field.

Updated registries of some mutations are beginning to appear on the internet, and eventually this may be the common means for providing access to mutations. In the meanwhile, the publication of up-to-date, authoritative lists of mutations in Blood Cells, Molecules and Diseases can fill the need. The commentaries that we encourage and publish provide an opportunity for these tabulations to be updated and, where needed, corrected by the readers These corrections will also appear on the internet and in the journal and become a part of the permanent record documenting the mutations covered. We encourage colleagues who are maintaining mutation databases to submit them to us for rapid publication. In this way we hope to provide those interested in the genetics of hematologic disease with a readily available and very up-to-date source of information concerning what mutations have been found and where more information can be obtained about them.

A total of 97 mutations or combination of mutations of the X-linked gene for glucose-6-phosphate dehydrogenase are now known to us Previous tabulations, providing somewhat more detailed information about these mutations (1,2) and comprehensive reviews of the deficiency (2,3) may be found in the cited sources and in OMIM on the World Wide Web (

The cDNA numbers shown in the table are based on the Genbank sequence with the accession number X03674 and the genomic numbers on the sequence with accession number X55448. In each case the A of the ATG start codon is numbered +1. Note that this numbering is different from that used in the GenBank files. It is necessary to subtract 470 from the GenBank cDNA sequence and 3350 from the GenBank genomic sequence to standardize these sequences to begin at the start codon.
