Dentatorubral-pallidoluysian atrophy (DRPLA) is a progressive disorder of ataxia, myoclonus, epilepsy, and progressive intellectual deterioration in children and ataxia, choreoathetosis, and dementia or character changes in adults. Onset ranges from before age one year to age 72 years; mean age of onset is 31.5 years. The clinical presentation varies depending on the age of onset. The cardinal features in adults are ataxia, choreoathetosis, and dementia. Cardinal features in children are progressive intellectual deterioration, behavioral changes, myoclonus, and epilepsy. [from GeneReviews]

Type 1 diabetes mellitus (T1D), also designated insulin-dependent diabetes mellitus (IDDM), is a disorder of glucose homeostasis characterized by susceptibility to ketoacidosis in the absence of insulin therapy. It is a genetically heterogeneous autoimmune disease affecting about 0.3% of Caucasian populations (Todd, 1990). Genetic studies of T1D have focused on the identification of loci associated with increased susceptibility to this multifactorial phenotype. The classic phenotype of diabetes mellitus is polydipsia, polyphagia, and polyuria which result from hyperglycemia-induced osmotic diuresis and secondary thirst. These derangements result in long-term complications that affect the eyes, kidneys, nerves, and blood vessels. [from OMIM]

Arrest of lung development in the cananicular stage (weeks 18 to 26 of human gestation) resulting in simplified acinar spaces, frequently with abundant intervening mesenchyme and no alveoli. In later arrest growth stages early saccular formations may be seen. May resemble the lobular maldevelopment often seen in alveolar capillary dysplasia/misaligment of the pulmonary veins without vein misalignment or marked hypertensive changes of the pulmonary arteries. [from HPO]

An inherited susceptibility or predisposition to developing type 1 diabetes mellitus that has material basis in mutation of the locus at chromosome 4q27. [from MONDO]
