recessive, x-linked (medicine)


recessive, x-linked


A gene on the X chromosome that expresses itself only when there is no different gene present at that locus (spot on the chromosome). For example, duchenne muscular dystrophy (dmd) is an x-linked recessive disorder. A dmd boy has the dmd gene on his sole x chromosome (and so is said to be hemizgous for dmd). Although it is much rarer, a girl can have dmd (by several different means as, for example, if she has the dmd gene on both her x chromosomes and so is homozygous for dmd).
