Ak. Sweatman et al., PHYSICAL MAPPING IN THE REGION OF THE BRUTON TYROSINE KINASE AND ALPHA-GALACTOSIDASE-A GENE LOCI IN PROXIMAL XQ22, Human genetics, 94(6), 1994, pp. 624-628
We have produced physical maps of the proximal part of Xq22, containin
g the Bruton's tyrosine kinase (BTK) and alpha a-galactosidase A (GLA)
gene loci, using long range physical mapping techniques and yeast art
ificial chromosomes (YACs). These maps reveal five previously unidenti
fied CpG islands which could indicate the presence of other genes in t
his region.
