    Abstract:
    Employing pulsed field gradient electrophoresis, we constructed a 4.5 million bp (Mb) Sfil restriction map of the human X-chromosomal region p21, harboring genes for Duchenne (DMD) and Becker Muscular Dystrophy. In a DMD patient with additional chronic granulomatosis and retinitis pigmentosa, the proximal 3.5 Mb is deleted. Another DMD patient, with additional glycerol kinase deficiency and adrenal hypoplasia, lacks at least 3.3 Mb in the middle region, including marker C7 but not B24, placing C7 closer to DMD. Another DMD patient has a partial pERT-87 deletion of minimally 140 kb. Truncated Sfil fragments in a female X:21 translocation patient place the junction probe XJ1.1 115 kb from the distal end of the normal fragment. Probe pERT-84 maps to the same fragment, within 750 kb of XJ1.1.
