PUM1-associated developmental disability-ataxia-seizure syndrome

What it is

A rare genetic syndromic intellectual disability characterized by developmental delay, intellectual disability, ataxia, and, more variably, seizures and short stature. Behavioral abnormalities may also be observed, as well as variable facial and other dysmorphic features (such as broad nasal bridge, hypertelorism, almond-shaped eyes, high-arched palate, and anomalies of the fingers and toes). Brain imaging may reveal dilated ventricles, small corpus callosum, or posterior fossa abnormalities.

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.
