Question: What are the symptoms of Pontocerebellar hypoplasia type 3 ?
Answer: What are the signs and symptoms of Pontocerebellar hypoplasia type 3? The Human Phenotype Ontology provides the following list of signs and symptoms for Pontocerebellar hypoplasia type 3. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Autosomal recessive inheritance - Brachycephaly - Cerebellar atrophy - Cerebellar hypoplasia - Cerebral atrophy - Congenital onset - Decreased body weight - Depressed nasal bridge - Downturned corners of mouth - Full cheeks - Hearing impairment - High palate - Hyperreflexia - Hypoplasia of the brainstem - Hypoplasia of the corpus callosum - Hypoplasia of the pons - Long palpebral fissure - Long philtrum - Low-set ears - Macrotia - Muscular hypotonia of the trunk - Neonatal hypotonia - Optic atrophy - Poor head control - Progressive - Progressive microcephaly - Proptosis - Seizures - Short stature - Spasticity - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
