• $18-Hydroxylase deficiency$: A rare genetic, metabolic defect where a deficiency of the enzyme 18-Hydroxylase which results in a reduced amount of aldosterone and salt wasting.
• $18p minus syndrome$: A rare chromosomal disorder where a portion of chromosome 18 is missing which is characterized by mental and growth deficiencies, drooping upper eyelid and prominent ears. The type and severity of symptoms is determined by the amount of genetic material that is missing.
• $1q deletion$: A rare chromosomal disorder where part of the long arm (q) of chromosome 1 is deleted resulting in various abnormalities which are determined by the size of the deleted portion.
• $2-Hydroxyglutaricaciduria$: A rare metabolic disorder characterized by high levels of a certain chemical (2-Hydroxyglutaric) which causes a serious progressive neurological disease and damage to the brain. The features of this disorder are variable and some cases are milder than others.
• $2-Methylbutyric Aciduria$: A very rare genetic disorder where an enzyme deficiency prevents the break down of certain proteins into energy and results in a harmful accumulation of acids in the blood and body tissues. More specifically, there is a deficiency of an enzyme (2-methylbutyryl-coenzyme A dehydrogenase) needed to convert the amino acid isoleucine into energy. 2-methylbutyrylglycine levels build up in the body and may cause damage. Symptoms vary according to the degree of enzyme deficiency - can range from asymptomatic to life-threatening.
