Index Allan–Herndon–Dudley syndrome

Allan–Herndon–Dudley syndrome is a rare X-linked inherited disorder of brain development that causes both moderate to severe intellectual disability and problems with speech and movement. [1]

Brain

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.

C. Nash Herndon

Claude Nash Herndon Jr. (February 23, 1916 – March 29, 1998) was an American human geneticist and eugenicist who taught at the Bowman Gray School of Medicine (now the Wake Forest School of Medicine).

Hypotonia

Hypotonia, commonly known as floppy baby syndrome, is a state of low muscle tone (the amount of tension or resistance to stretch in a muscle), often involving reduced muscle strength.

Intellectual disability

Intellectual disability (ID), also known as general learning disability, and mental retardation (MR), is a generalized neurodevelopmental disorder characterized by significantly impaired intellectual and adaptive functioning.

Monocarboxylate transporter 8

Monocarboxylate transporter 8 (MCT8) is an active transporter protein that in humans is encoded by the SLC16A2 gene.

Nervous system

The nervous system is the part of an animal that coordinates its actions by transmitting signals to and from different parts of its body.

Neuron

A neuron, also known as a neurone (British spelling) and nerve cell, is an electrically excitable cell that receives, processes, and transmits information through electrical and chemical signals.

Santiago de Compostela

Santiago de Compostela is the capital of the autonomous community of Galicia, in northwestern Spain.

Spasticity

Spasticity is a feature of altered skeletal muscle performance with a combination of paralysis, increased tendon reflex activity, and hypertonia.

Synapse

In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target efferent cell.

Thyroid

The thyroid gland, or simply the thyroid, is an endocrine gland in the neck, consisting of two lobes connected by an isthmus.

Tiratricol

Tiratricol (also known as TRIAC or triiodothyroacetic acid) is a thyroid hormone analogue.

Wheelchair

A wheelchair, often abbreviated to just "chair", is a chair with wheels, used when walking is difficult or impossible due to illness, injury, or disability.

William Allan (geneticist)

William Allan (1881–1943) was an American physician and geneticist who made pioneering studies in human genetics and hereditary diseases.

X-linked recessive inheritance

X-linked recessive inheritance is a mode of inheritance in which a mutation in a gene on the X chromosome causes the phenotype to be expressed in males (who are necessarily hemizygous for the gene mutation because they have one X and one Y chromosome) and in females who are homozygous for the gene mutation, see zygosity.
