Anonychia
Anonychia
Anonychia (/əˈnɒnɪkiə/), from the Greek words "an-" (without) and "onyx" (nail), is a rare congenital condition characterized by the absence of fingernails and toenails. This condition may be complete or partial, affecting one or more nails.
Definition
Anonychia is a medical term that refers to the absence of nails, a condition that can be present at birth or develop later in life. It can affect both the fingernails and toenails, and can be either complete (all nails are absent) or partial (some nails are absent).
Causes
Anonychia is often associated with a number of genetic disorders, including DOOR syndrome, Ectodermal dysplasia, and Iso-Kikuchi syndrome. It can also occur as an isolated condition, with no other apparent abnormalities.
Symptoms
The primary symptom of anonychia is the absence of nails. This can lead to functional difficulties, such as problems with fine motor skills. In some cases, the condition may also be associated with other abnormalities, such as hearing loss or intellectual disability.
Treatment
There is currently no cure for anonychia. Treatment is focused on managing the symptoms and any associated conditions. This may include physical therapy to improve fine motor skills, or hearing aids for those with hearing loss.
