	'''Elejalde syndrome''', also known as '''neuroectodermal melanolysosomal disease''', is a rare [[genetic disorder]] characterized by a combination of [[neurological]], [[dermatological]], and [[ocular]] abnormalities. It is an [[autosomal recessive]] condition, meaning that an individual must inherit two copies of the mutated gene, one from each parent, to be affected by the disorder.

==Symptoms and Characteristics==
The primary features of Elejalde Syndrome include:

* '''Hypopigmentation:''' Individuals with ES exhibit a marked reduction in melanin, leading to lighter skin, hair, and eye color than unaffected family members.
* '''Neurological Impairment:''' Severe mental retardation, seizures, and muscle hypotonia are common among those affected.
* '''Facial Dysmorphology:''' Distinctive facial features may include a broad nasal bridge, hypertelorism (widely spaced eyes), and epicanthic folds.
* '''Growth Retardation:''' Affected individuals may experience delayed growth and development.

* '''Genetic Counseling:''' To provide affected families with information about the condition and its inheritance pattern.

==Prognosis==
The prognosis for individuals with Elejalde Syndrome varies depending on the severity of symptoms. Neurological impairment is typically severe, and affected individuals may require lifelong care and support. Early intervention and supportive therapies can improve the quality of life for those with ES.
