Autosomal recessive pattern, showing how two unaffected carriers can have a child with the disease. Some genetic disorders are caused by having two "bad" copies of a recessive allele. When the gene is located on an autosome (as opposed to a sex chromosome), it is possible for both men and women to be carriers .
X-linked recessive inheritance. X-linked recessive inheritance is a mode of inheritance in which a mutation in a gene on the X chromosome causes the phenotype to be always expressed in males (who are necessarily hemizygous for the gene mutation because they have one X and one Y chromosome) and in females who are homozygous for the gene mutation, see zygosity.
[24] [25] Some autosomal recessive disorders are common because, in the past, carrying one of the faulty genes led to a slight protection against an infectious disease or toxin such as tuberculosis or malaria. [26] Such disorders include cystic fibrosis, [27] sickle cell disease, [28] phenylketonuria [29] and thalassaemia. [30]
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
McLeod syndrome (/ m ə ˈ k l aʊ d / mə-KLOWD) is an X-linked recessive genetic disorder that may affect the blood, brain, peripheral nerves, muscle, and heart.It is caused by a variety of recessively inherited mutations in the XK gene on the X chromosome.

Most of these disorders involve excessive or deficient production of hormones such as glucocorticoids, mineralocorticoids, or sex steroids, [4] [2] and can alter development of primary or secondary sex characteristics in some affected infants, children, or adults. [5] It is one of the most common autosomal recessive disorders in humans. [6] [7] [8]
