Carrier detection in X-linked immunodeficiencies. I: A PCR-based X chromosome inactivation assay at the MAOA locus.
We developed an X chromosome inactivation PCR assay, based on differential methylation of the 5' CpG island of the monoamine oxidase A gene (MAOA), close to a highly polymorphic region just downstream of the first exon. The assay provides a method to determine the carrier status of females from pedigrees with X-linked immunodeficiency diseases (XLID).
