Figure Pedigree of an X-linked dominant disorder. Normal red blood cells live about days in the bloodstream, but sickled red cells die after about 10 to 20 days. Carrier females who have only one copy of the mutation do not usually express the phenotype, although differences in X-chromosome inactivation known as skewed X-inactivation can lead to varying degrees of clinical expression in carrier females, since some cells will express one X allele and some will express the other.

They may also experience a lack of concentration and focus. See also: X-linked intellectual disability.
