In childhood, a short stature can be indicative of Turner syndrome.A test called a karyotype, also known as a chromosome analysis, analyzes the chromosomal composition of the individual. This is the test of choice to diagnose Turner syndrome. Treatment
As a chromosomal condition, there is no cure for Turner syndrome. However, much can be done to minimize the symptoms. While most of the physical findings are harmless, significant medical problems can be associated with the syndrome. Most of these significant conditions are treatable with surgery and other therapies including hormonal therapy. Growth hormone, either alone or with a low dose of androgen, will increase growth and probably final adult height. Growth hormone is approved by the U.S. Food and Drug Administration for treatment of Turner syndrome and is covered by many insurance plans. There is evidence that this is effective, even in toddlers. A 2019 systematic review comparing effects of adding oxandrolone to growth hormone treatment to growth hormone alone has found moderate-quality evidence that the addition of oxandrolone leads to an increase in final adult height of girls with Turner syndrome. When the same review assessed the effects of adding Oxandrolone to growth hormone treatment on speech, cognition and psychological status, the results were inconclusive due to very-low quality evidence. Estrogen replacement therapy such as the birth control pill, has been used since the condition was described in 1938 to promote development of secondary sexual characteristics. Estrogens are crucial for maintaining good bone integrity, cardiovascular health and tissue health.
HDLS commonly manifests with neuropsychiatric symptoms, progressing to dementia, and after a few years shows motor dysfunction. Eventually patients become reliant on wheelchairs.White matter degeneration is associated with and makes differential diagnoses out of other adult onset leukodystrophies such as metachromatic leukodystrophy (MLD), Krabbe disease (globoid cell leukodystrophy), and X-linked adrenoleukodystrophy (X-ADL). Neuropsychiatric symptoms
Many neuropsychiatric symptoms have been identified in clinical studies of HDLS patients. These include severe depression and anxiety that have been identified in about 70% of HDLS families, verging on suicidal tendencies and substance abuse such as alcoholism. Additionally, patients may exhibit disorientation, confusion, agitation, irritability, aggressiveness, an altered mental state, the loss of the ability to execute learned movements (apraxia), or the inability to speak (mutism). Motor impairment
Persons with HDLS can develop tremors, decreased body movement, unsteadiness (Parkinsonism, muscles on one side of the body in constant contraction (spastic hemiparesis), impairment in motor and sensory function in the lower extremities (paraparesis), paralysis resulting in partial or total loss of all extremities and torso (tetraparesis), and the lack of voluntary coordination of muscle movements (ataxia). Causes
The cause of HDLS in most families is mutation in the colony stimulating factor 1 receptor (CSF1R), a growth factor for microglia and monocyte/macrophages, suggesting that microglial dysfunction may be primary in HDLS.The mutations are concentrated in tyrosine kinase domain (TKD) of the protein.
