Ichthyosis (also named fish scale disease) [1] is a family of genetic skin disorders characterized by dry, thickened, scaly skin. [2] The more than 20 types of ichthyosis range in severity of symptoms, outward appearance, underlying genetic cause and mode of inheritance (e.g., dominant, recessive , autosomal or X-linked ). [ 3 ]
Ichthyosis vulgaris (also known as "autosomal dominant ichthyosis" [1] and "Ichthyosis simplex" [1]) is a skin disorder causing dry, scaly skin. It is the most common form, and one of the mildest forms, of ichthyosis, [2] [3]: 486 affecting around 1 in 250 people. [4] For this reason it is known as common ichthyosis.

X-linked ichthyosis (abbreviated XLI) is a skin condition caused by the hereditary deficiency of the steroid sulfatase (STS) enzyme that affects 1 in 2000 to 1 in 6000 males. [2] XLI manifests with dry, scaly skin [ 3 ] and is due to deletions [ 4 ] [ 5 ] or mutations [ 6 ] in the STS gene.
Acute lymphoblastic leukemia is the most common type of cancer in children, accounting for ~30% of cases. [2] However, far more adults than children develop lymphoma and leukemia. Germ cell tumor : Cancers derived from pluripotent cells, most often presenting in the testicle or the ovary ( seminoma and dysgerminoma , respectively).
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.
