Question: What are the symptoms of Summitt syndrome ?
Answer: What are the signs and symptoms of Summitt syndrome? The Human Phenotype Ontology provides the following list of signs and symptoms for Summitt syndrome. 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) Brachydactyly syndrome 90% Clinodactyly of the 5th finger 90% Craniosynostosis 90% Epicanthus 90% Finger syndactyly 90% Genu valgum 90% Hypertelorism 90% Macrocephaly 90% Narrow face 90% Obesity 90% Plagiocephaly 90% Prominent metopic ridge 90% Tall stature 90% Abnormality of the metacarpal bones 50% Depressed nasal ridge 50% Strabismus 50% Cryptorchidism 7.5% Depressed nasal bridge 7.5% Hypoplasia of penis 7.5% Low-set, posteriorly rotated ears 7.5% Autosomal recessive inheritance - Oxycephaly - Syndactyly - 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.
