(a) Linkage analysis showing LOD score of 6.82 at chromosome 10q21–22. Shaded bar indicates the 11.1 cM shared haplotype region spanning 8.2 Mb and containing 48 genes. (b) Location of 3 novel disease-associated variants in non-coding regions of HK1. The promoters of the three HK1 isoforms are identified: PT (testes specific), PE (erythrocyte specific), and PU (ubiquitous). Tissue specific exons are designated T1-T6 and E1. Exons 2–18 are shared by all 3 isoforms. Transcription start sites are indicated with arrows.
