What it is

Olivopontocerebellar atrophy-deafness syndrome is characterised by infancy-onset olivopontocerebellar atrophy, sensorineural deafness and speech impairment. It has been described in less than 15 children. Most cases were sporadic, but autosomal recessive inheritance was suggested in three cases.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

Q04.8filed under a broader ICD-10 category — shared with 40 other rare diseases

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.
