Thyroid hormone resistance, generalized, autosomal dominant

An autosomal dominant disease characterized by high levels of circulating thyroid hormones (T3-T4), goiter, abnormal mental functions, increased susceptibility to infections, abnormal growth and bone maturation, tachycardia and deafness. Affected individuals may also have attention deficit-hyperactivity disorders (ADHD) and language difficulties. Patients have normal or slightly elevated thyroid stimulating hormone (TSH).

Atrial septal defect 7, with or without atrioventricular conduction defects

A congenital heart malformation characterized by incomplete closure of the wall between the atria resulting in blood flow from the left to the right atria, and atrioventricular conduction defects in some cases.

Bamforth-Lazarus syndrome

An autosomal recessive disease characterized by congenital hypothyroidism due to thyroid agenesis or thyroid hypoplasia, cleft palate, spiky hair, with or without choanal atresia, and bifid epiglottis.

Pendred syndrome

An autosomal recessive disorder characterized by congenital sensorineural hearing loss in association with thyroid goiter. The disorder may account for up to 10% of the cases of hereditary deafness. The deafness is most often associated with a Mondini cochlear defect. Deafness occurs early, starting at birth or during the first years of life. It is bilateral, sometimes asymmetrical, fluctuant and often progressive. Thyroid perturbations, such as thyroid goiter and/or hypothyroidism appear most commonly during adolescence, but they can be congenital or appear later.

Hypothyroidism, congenital, non-goitrous, 2

A disease characterized by thyroid dysgenesis, the most frequent cause of congenital hypothyroidism, accounting for 85% of case. The thyroid gland can be completely absent (athyreosis), ectopically located and/or severely hypoplastic. Ectopic thyroid gland is the most frequent malformation, with thyroid tissue being found most often at the base of the tongue.

Chorea, hereditary benign

A rare autosomal dominant movement disorder, defined by early onset in childhood, a stable or non-progressive course of chorea, and no mental deterioration. Chorea is characterized by involuntary, forcible, rapid, jerky movements that may be subtle or become confluent, markedly altering normal patterns of movement.
