MIXL localizes to human chromosome 1q42.MIXL was localized to human chromosome 1q42 and linked to the markers in bold by radiation hybrid mapping. Tentative genomic sequences from BACs 216I11, RP11-588H15, and RP11-275I14 contain theMIXL gene. BACs 588H15 and 275I14 also span the marker SHGC-37008. BAC RP11-15H13, which overlaps with BAC 588H15, contains the marker SHGC-30345. BAC RP11-396C23 overlapping with BAC 275I14 contains the microsatellite marker D1S479. The microsatellite markers D1S479 and D1S459 (in text box) localize to band 1q42.12 and 1q42.2b by high-resolution FISH.
