Question: What are the symptoms of Stargardt macular degeneration absent or hypoplastic corpus callosum mental retardation and dysmorphic features ?
Answer: What are the signs and symptoms of Stargardt macular degeneration absent or hypoplastic corpus callosum mental retardation and dysmorphic features? The Human Phenotype Ontology provides the following list of signs and symptoms for Stargardt macular degeneration absent or hypoplastic corpus callosum mental retardation and dysmorphic features. 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) Agenesis of corpus callosum - Autosomal recessive inheritance - Broad eyebrow - Broad nasal tip - Clinodactyly of the 5th finger - Dental crowding - Full cheeks - High palate - Hypoplasia of the corpus callosum - Intellectual disability - Large earlobe - Macular degeneration - Pes planus - Pointed chin - Poor eye contact - Sensorineural hearing impairment - Smooth philtrum - Strabismus - Upslanted palpebral fissure - 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.
