NESCAV syndrome

What it is

A rare syndromic neurodegenerative syndrome characterized by infancy/childhood-onset global developmental delay, poor or absent speech, moderate to severe intellectual disability, hypotonia, progressive spasticity (mainly affecting the lower limbs and leading to walking difficulties or loss of independent ambulation), and peripheral axonal neuropathy. The clinical presentation varies among affected individuals and other major clinical features include progressive cerebellar atrophy (in some patients cerebral atrophy may also be present), postnatal microcephaly, cortical visual impairment (associated with optic atrophy), seizures, hyperreflexia, dysautonomia, ataxia, dystonia, behavioral abnormalities and feeding difficulties. Joint contractures, scoliosis and kyphosis may also be present.

Disease

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
