Thyroid appearance of cells is viewed to determine whether they resemble normal or cancerous cells. There can be many nodules, which is termed a multinodular goitre, and this can sometimes be a toxic multinodular goitre. An enlarged thyroid gland is called a goitre. Goitres are present in some form in about 5% of people, and are the result of a large number of causes, including iodine deficiency, autoimmune disease (both Grave's disease and Hashimoto's thyroiditis), infection, inflammation, and infltrative disease such as sarcoidosis and amyloidosis. Sometimes no cause can be found, a state called "simple goitre". Some forms of goitre are
ZC4H2 deficiency neurological manifestations. These can include: To date, there is no cure or effective treatment for this condition. Current approach is limited to supportive therapies and interventions. ZC4H2 deficiency ZC4H2 (Zinc finger C4H2-type) is a protein-coding gene located on the X-chromosome. This gene encodes a protein which is a member of the so-called zinc finger domain-containing protein family. There is currently very limited understanding about the ZC4H2 gene and its protein function. Any pathogenic variant of ZC4H2 which is associated with a clinical phenotype is referred to as "ZC4H2 Deficiency". The limited research published to date indicates that ZC4H2 is expressed
