• Wolfram Syndrome 2: Wolfram Syndrome is a condition characterized by the association of diabetes insipidus, diabetes mellitus, optic atrophy and deafness. Type 2 is the result of a genetic defect and is similar to type 1 but there is no diabetes insipidus and patients tend to develop gastrointestinal problems.
• Worster Drought syndrome: A mild form of tetraplegic cerebral palsy
• X chromosome, duplication Xq13 1 q21 1: A condition characterised by the duplication of the long arm of chromosome X.
• X chromosome, trisomy 26-28: A condition characterised by the duplication of the long arm of chromosome X.
• X chromosome, trisomy Xp3: A condition characterised by the duplication of the long arm of chromosome X.
• X chromosome, trisomy Xpter Xq13: A condition characterised by the duplication of the long arm of chromosome X.
• X chromosome, trisomy Xq: A condition characterised by the duplication of the long arm of chromosome X.
• X chromosome, trisomy Xq25: A condition characterised by the duplication of the long arm of chromosome X.
• X-Linked Agammaglobulinemia: Immune deficiency from lack of antibodies.
• X-linked alpha thalassemia mental retardation syndrome (ATR-X): An x-linked condition that features mental retardation, dysmorphic features, and alpha thalassemia
• X-linked lymphoproliferative syndrome: A rare inherited immunodeficiency disorder where the body's immune systm is unable to respond appropriately to certain viral infections (Epstein Barr virus).
• X-linked mental retardation craniofacial abnormal microcepahly club: An x-linked condition that is characterised by mental retardation and dysmorphic facies
• X-linked sideroblastic anemia: X-linked sideroblastic anemia is a rare inherited blood disorder characterized by abnormal deposits of iron in the red blood cells which makes them unable to function properly. The body continues to absorb more iron from digesting food in order to try and correct the problem but this simply leads to excessive iron being deposited in body tissues as the it can't use the iron properly. The severity of the condition is variable.
• Xanthogranulomatous sialdenitis: Xanthogranulomas and inflammation of the salivary glands
• Xanthophobia: An exaggerated or irrational fear of the color yellow or the word yellow.
• Xenophobia: An exaggerated or irrational fear or hatred of foreigners and strange things.
• Xeroderma pigmentosum: A rare pigmentary disease that is caused by an enzyme deficiency
• Xeroderma pigmentosum, type 1: A rare genetic disorder where the enzyme that repairs DNA damage done by UV radiation is defective. It is characterized by sensitivity to sunlight, skin pigmentation and atrophy and actinic skin tumors. The different types of xeroderma pigmentosum vary in the body's ability to repair the damage to DNA done by UV radiation - type 1 has the lowest level of repair and the most neurological complications.
• Xeroderma pigmentosum, type 2: A rare genetic disorder where the enzyme that repairs DNA damage done by UV radiation is defective. It is characterized by sensitivity to sunlight, skin pigmentation and atrophy and actinic skin tumors. The different types of xeroderma pigmentosum vary in the body's ability to repair the damage to DNA done by UV radiation. Type B is often associated with signs of Cockayne syndrome.
• Xeroderma pigmentosum, type 3: A rare genetic disorder where the enzyme that repairs DNA damage done by UV radiation is defective. It is characterized by sensitivity to sunlight, skin pigmentation and atrophy and actinic skin tumors. The different types of xeroderma pigmentosum vary in the body's ability to repair the damage to DNA done by UV radiation. Neurological symptoms are rarely experienced in type 3.
• Xeroderma pigmentosum, type 4: A rare genetic disorder where the enzyme that repairs DNA damage done by UV radiation is defective. It is characterized by sensitivity to sunlight, skin pigmentation and atrophy and actinic skin tumors. The different types of xeroderma pigmentosum vary in the body's ability to repair the damage to DNA done by UV radiation. Type D involves neurological symptoms.
• Xeroderma pigmentosum, type 6: A rare genetic disorder where the enzyme that repairs DNA damage done by UV radiation is defective. It is characterized by sensitivity to sunlight, skin pigmentation and atrophy and actinic skin tumors. The different types of xeroderma pigmentosum vary in the body's ability to repair the damage to DNA done by UV radiation. The skin and neurological symptoms in Type 6 tend to be mild.
• Xeroderma pigmentosum, type 7: A rare genetic disorder where the enzyme that repairs DNA damage done by UV radiation is defective. It is characterized by sensitivity to sunlight, skin pigmentation and atrophy and actinic skin tumors. The different types of xeroderma pigmentosum vary in the body's ability to repair the damage to DNA done by UV radiation. Type G usually involves severe neurological symptoms.
• Xerophobia: An exaggerated or irrational fear of dryness and dry places such as deserts.
• Yellow fever: A viral infection transmitted by mosquito bites which can damage various organs such as the liver, heart, kidney and digestive tract.
• Young Simpson syndrome: A condition that is characterised by mainly mental retardation and physical signs of hypothyroidism
• Zadik Barak Levin syndrome: A condition that affects the endocrine system as well as some facial characteristics
• Zellweger Syndrome: Zellweger spectrum disorders are a group of rare, genetic, multisystem disorders that were once thought to be separate entities. These disorders are now classified as different expressions (variants) of one disease process. Collectively, they form a spectrum or continuum of disease. Zellweger syndrome is the most severe form; neonatal adrenoleukodystrophy is the intermediate form; and infantile Refsum disease is the mildest form.
• Zelophobia: An exaggerated or irrational fear of jealousy.
• Zemmiphobia: An exaggerated or irrational fear of the great mole rat.
• Zlotogora syndrome: A condition that is characterised by facial dysmorphism and psychiatric problems
• Zoophobia: An exaggerated or irrational fear of animals.
