The Human Phenotype Ontology provides the following list of signs and symptoms for Congenital myasthenic syndrome associated with acetylcholine receptor deficiency. 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) Abnormality of the immune system - Autosomal recessive inheritance - Decreased fetal movement - Decreased muscle mass - Decreased size of nerve terminals - Dental malocclusion - Dysarthria - Dysphagia - Easy fatigability - EMG: decremental response of compound muscle action potential to repetitive nerve stimulation - Facial palsy - Feeding difficulties - Gowers sign - High palate - Infantile onset - Long face - Mandibular prognathia - Motor delay - Muscle cramps - Muscular hypotonia - Nonprogressive - Ophthalmoparesis - Ptosis - Respiratory insufficiency due to muscle weakness - Skeletal muscle atrophy - Strabismus - Type 2 muscle fiber atrophy - Variable expressivity - Weak cry - 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.
